How to choose and install a lock for plastic doors. Locks for plastic doors: types, selection and operating tips

A plastic door differs from analogues made from other materials in its multi-layer structure, so the locks for such doors also differ from their counterparts. Lock for plastic door installed by professionals. People who are not familiar with the design features of the door leaf are recommended to install only certain types of products themselves. They will be discussed in our article.

Lock selection criteria

When choosing a lock, you should rely on two important factors:

• the type of lock that determines its reliability;
• quality of the locking device provided by the manufacturers.

Types of castles

Locks for plastic doors come in mortise and overhead locks. Mainly used mortise mechanisms, without spoiling the appearance of the door leaf.

According to the locking mechanism, locks are:

• lever - the closing mechanism is formed by several plates;
• cylinder - the lock cylinder is a cylinder in which the pins move in a certain order;
• electronic - locked using a key fob, chip, etc.;
• electromagnetic - in addition to the electronic mechanism, they are equipped with magnets that hold the door in the closed position;
• multi-locking - the locking mechanism is based on several elements of different types.

For plastic doors, in most cases, electromagnetic and multi-point locks are used, since with a small design they provide maximum reliability.

All plastic locks are different from their counterparts small in size and lightweight design.

• cylinder locks with a small cylinder;
• latch handles with additional locking with a key (installed on most balcony doors);

• Magnetic clasp handles. The door is fixed due to the action of a strong magnet;

• roller latches. The roller is under the influence of a spring. When the door is closed, the spring weakens and the roller fits into a groove specially marked for it, thereby fixing the door.

Balcony locks are not secure. For additional protection of the apartment from “window openers”, it is recommended to install a security alarm.

Manufacturers of locks for plastic doors

On Russian market The most common locks from such companies are:

• Apex;
• Calais;
• Guardian.

A lock for a plastic door from Apex costs approximately 600-700 rubles (at the time of publication). The company primarily produces multi-locking devices. All products Chinese manufacturer certified in Russia. It is produced in accordance with GOST and is durable (all products are designed for more than 200 thousand opening and closing cycles).

The cost of locks from the Turkish company Kale is slightly higher (approximately 1,000 rubles). Just like the previous company, Kale is engaged in the production of multi-point locks. Products are made from high-strength materials that are not subject to corrosion. All devices have high class burglary protection.

The Russian company Guardian produces a wider range of locks for plastic doors. The average cost of one product is 550 rubles. The manufactured products are certified. The lineup constantly changing, adapting to the needs of customers.

Each manufacturer gives a factory guarantee for its products, which indicates the quality of the products.

Installation of locks

For balcony doors the most simple solution There will be a replacement of a regular handle with a product that can be locked with a key. This operation Even a person without experience can do it by watching the video instructions provided.

As mentioned earlier, it is best to entrust the installation of complex locks to a plastic door to specialists, but if you decide to carry out the work yourself, then you need to follow the following instructions.

Installation of an electromagnetic lock

To connect electromagnetic lock electricity supply is required. Installation of the device is carried out as follows:

1. As with the installation of other types of locks, at the first stage the holes are marked for subsequent fastening of the device. The electromagnetic lock consists of two parts that fit tightly to each other, so marking must be carried out as accurately as possible, and in turn - first one part, then the other;

1. holes are drilled in the marked areas, the depth of which is equal to the size of the mounting screw;
2. both parts of the electromagnetic lock are installed and fixed;

1. Each lock comes with connection instructions, according to which electric wires and the terminals are connected;

1. on last stage Connection is made to the power source and the functionality of the mechanism is checked. If any problems are detected, steps 3-5 need to be checked and corrected if necessary.

If desired or necessary, you can connect additional devices to such a lock, for example, a closer or a video intercom.

Installation of a multi-point lock

Multi-point locks represent an entire door locking system. It consists of the following elements:

• the main mechanism, which can be of a crossbar or non-crossbar type;
• auxiliary roller or flange lock;
• a frame connecting all elements of the lock into a single system;
• movable bus;
• additional trunnions.

Multi-point lock

Due to the complexity of the device and the high precision during installation, it is not recommended to install the lock on your own.

Locks for plastic doors are quite varied. Some of them can be installed independently (mortise lever or cylinder, electromagnetic, etc.), while others (multi-port) only with the help of specialists. Each lock is unique in its own way and has a high degree of security. For long-term and uninterrupted operation For devices, it is recommended to purchase locks from the most well-known manufacturers.

The door made of plastic is quite popular. And it is used not only as a balcony, but can also be an entrance or interior. That's why a lock is needed. But before you buy a locking mechanism, you need to know what types of locks there are and whether they should be mounted on a particular PVC door.

Features of locks for plastic doors

First of all, it is worth noting that the lock for a plastic entrance door differs from the lock installed on a balcony or interior door from PVC. And these differences are quite significant. In addition, a lock that is embedded into metal or wooden doors is in no way suitable for PVC sheets.

The whole nuance lies in the design of the plastic sheet. The basis of such a door is a double-glazed window and a sandwich panel. In fact, the structure is similar to the usual plastic windows, only less glazed (although this option is also present) and more massive.

The lock on a plastic door has certain dimensions that correspond to the width of the profile. Typically, mortise locking mechanisms are used. But if necessary, you can also install invoices.

Classification of locks

As mentioned earlier, locks can be:

• overhead, that is, mounted on the surface of the door;
• mortise, respectively, are installed inside the door leaf.

According to the material, the mechanisms are:

• partially plastic;
• metal.

By number of locking points door lock for a plastic door it can be:

• Single lock. It only has one locking point in the middle. As a result, the door does not fit tightly and does not provide reliable protection.
• A multi-point lock on a plastic door has two or more points of contact with the frame. This mechanism is more reliable.

Castles are also divided into the following types:

• level;
• cylinder;
• electronic;
• electromagnetic;
• electromechanical.

Let's look at the types of locking mechanisms in more detail.

Level castle

This type of lock is rarely installed on a plastic door. It is more suitable for wooden or metal doors. The locking mechanism itself is opened with a key.

A lever-type lock consists of plates with rectangular teeth. They allow the plates to line up in the desired order, which is unique to each product.

The main advantages of such a castle are: low price and prevalence. The main disadvantage is low resistance to hacking. It is also worth noting that if you lose the key, it will not be possible to replace only part of the lock. That is, the entire mechanism will have to be changed completely.

Cylinder lock

This type of mortise lock for a plastic door is also rarely used. First of all, it is intended for installation on metal and wooden doors.

The basis is for a plastic door and cylindrical pins. You can open such a lock using a key with slots on the working part. When the key is turned, the pins are positioned in the correct combination and the lock opens.

If the key to such a lock is lost, the entire mechanism does not need to be changed. Only the larva changes.

Electronic lock type

New type a castle that appeared on the market relatively recently. To open such a lock, a remote control, key fob, electronic card or chip are used.

Such a lock is usually installed on a plastic door when designing a private house.

The main advantage of such a mechanism is its ease of use. It is believed that such locking devices are quite reliable. But at the moment of a power outage, the door will become an insurmountable barrier.

A distinctive point is the ability to transfer information to a computer about the number of visits. Such systems are still used in big companies and in factories, which allows you to find out which employee arrived and left at what time.

Electromechanical lock

This type of lock has several types of protection. Most often this electronic protection and latch. provides for the presence of crossbars. But you can open it either with a key or by using electronic device(key fob, card, etc.).

An electromechanical lock for a plastic door is quite expensive. And yet, it is much more reliable than conventional electronic or mechanical locks. Such locks are often used in banks and various storage facilities.

Electromagnetic lock

Difference between electromagnetic and electromechanical locks not great. Instead of crossbars, the mechanism is equipped with special magnets. This lock will only work if there is power.

The mechanism tightly fixes the door when closed, the holding force can be up to 1 ton. An important advantage It should be mentioned that, having no mechanical parts, the lock hardly wears out. Open locking device The most convenient way is to use a key fob.

Balcony door lock

The balcony door differs in design from other plastic doors. This door is multifunctional: ventilation mode, opening, position fixation. Accordingly, the lock on the plastic balcony door must be equipped with a handle.

Essentially a security function balcony door does not fulfill. Therefore, a latch handle is most often used. The price of a lock for a plastic door with a handle is not high, but the degree of reliability is also low.

Latch handles can also be equipped with additional electronic or magnetic devices.

How to choose a lock, what to look for when buying?

The choice of lock for a plastic door depends on several factors. First of all, this is the size of the castle. It depends on the type of door and where it will be installed. The next factor is single or multiple locking mechanism needed.

The first is installed when the doors are located indoors. That is, there are no temperature changes and no protection against burglary is needed. If a closer is not installed, then it is better to give preference to a door with a halyard latch with an additional pressure device.

If there is a closer, choose a latch with a roller mechanism. In this case, a push handle is not needed, a regular one will suffice. That is, the door is fixed thanks to the closer, and not the roller.

If the plastic door is located between warm room and a cold street (that is, it serves as an external one), then it is better to use a multi-point lock. It will press the door leaf at several points, which will avoid drafts and ice freezing in winter.

In general, when buying locks you need to pay attention not only to appearance, but also for other qualities. When choosing lever locks, you need to take into account the material, number of levers and burglary resistance class. In cylindrical mechanisms, security, material and tamper resistance, as well as functionality are also important.

When choosing electric mechanical lock its features are taken into account. For example, are there hidden elements and their location. They help protect the device from hacking. Appearance, reliability and material of manufacture are also important. At the time of buying electromagnetic locks You need to pay attention to the build quality of the mechanism and its materials.

If the choice falls on a multi-point lock, pay attention to the number of elements, quality and material. For latch handles, appearance and the absence of any inconvenience when pressing the handle are important.

Installing a lock on a plastic door

It is worth noting that installing a regular lock or latch is not difficult. Except for multi-point locks. It is better to entrust their installation to a specialist, otherwise there is a risk of simply ruining the door.

The installation process will be described using the example of an electromagnetic lock.

1. Marking. All positions of the mechanism are carefully marked and required holes.
2. Holes. Depending on the type of lock, you need to drill holes. Their depth depends on the selected mounting screws.
3. Installation of lock parts. The electromagnetic lock has two parts. One of them is mounted in the opening, and the other is attached directly to the door leaf itself. It is at this step that both parts are mounted in place.
4. Electronics. It is not possible to describe the connection in more detail, since each electromagnetic mechanism is connected in its own way. That is, in every specific situation you must follow the instructions included with the device.
5. Power connection. According to the instructions, the lock is connected to the power supply.
6. Functionality check. This The final stage, but it is extremely important. When properly installed and connected, the door should be securely locked in the closed position, and opening should be easy, without any hitches.

Be that as it may, if there are doubts about the possibility self-installation, it is better to contact a specialist. Of course, the service for a plastic door costs money. But on the other hand, a damaged door leaf can be much more expensive.

Finally

Plastic doors are used not only on balconies, but also as interior and entrance doors. Therefore, choosing a lock is a responsible task. It is worth considering not only the type of mechanism, but also a number of other nuances such as installation location, material, quality, etc. The process of installing a lock on a plastic door is not complicated, but it is still better to entrust the installation of some types of locking devices to specialists.

Sections of the article:

In order to choose the right locks for plastic doors, you need to know about their features and distinctive features. The fact is that the design of plastic doors differs from the design of leaves made using other materials, which determines a different method of inserting locking mechanisms and different selection criteria. ABOUT various types locks, their design features and selection criteria will be discussed in our article.

Features of locks for PVC doors

It is impossible to embed a locking mechanism designed for a metal, wooden, or any other door into plastic; such an operation is guaranteed to damage the door leaf. In this regard, there are special locks on the market for doors made of plastic. Such devices have a special body size that matches the width of the profile, which allows the locking mechanism not to rest against the glass unit or filler.

As a rule, mortise locks are installed in plastic panels, which allows you to maintain the attractive and aesthetic appearance of the entire structure. However, if there is a need to provide additional protection against burglary, rim locks can also be installed.

Types of locks installed on PVC doors

There are many types of locking mechanisms on the market. When choosing them, it is necessary to proceed from where the blade is installed, what requirements are imposed on the reliability of the lock and many other factors.

As already noted, the lock on a plastic door can be either mortise or padded. Locking devices may vary design features, which determine their functionality. Let's look at the main types of locking mechanisms installed on plastic doors.

Depending on the number of locking points, single-locking or multi-locking options are distinguished.

Single-point locks have only one locking point and do not provide reliable protection and a tight fit between the door and the door leaf. The door does not fit tightly, since the single-point lock presses it only at the insertion point, that is, exactly in the middle of the structure.

Multi-point locks are a locking mechanism used to securely lock plastic doors with two or more points to achieve the greatest burglary protection. The locks have two or more points of contact with the box (two or more locks), which ensures the reliability of the structure, as well as the tight fit of the canvas to the box.

The locking devices are separated from each other and are driven by a special movable tire. Thanks to this design and the tight fit of the canvas to the frame, excellent sound insulation is achieved. In addition, heat does not escape from the room.

The locking mechanism does not allow the canvas to sag and the structure does not become loose. The considered locks for plastic doors are equipped with a cylinder standard view, or levers.

Depending on the material of manufacture, locks for plastic doors can be partially plastic or completely metal. Metal options are most widely distributed because they have greater strength and improved consumer qualities. It is recommended to choose metal.

Depending on the type of locking mechanism (single-lock or multi-lock), the options for locks and latches differ. The single-locking mechanism is equipped with a latch and a bolt, a latch and a roller, or a separate bolt and a latch.

Multi-locking mechanisms are divided into two main types: driven by a handle or driven by a cylinder.

The first option works as follows: when you turn the handle, the trunnions enter the corresponding strips and the canvas is pressed against the box. The key extends the bolt and locks the lock.

The second option simultaneously extends the trunnions and closes the bolt when turning the key.

There are also lever and cylinder locks.

The lever lock contains steel plates that are moved using protrusions on the key. Such locking mechanisms are more reliable than cylinder ones.

Cylinder lock works on a different principle. A larva is installed inside it, in which the pins are located. When you turn the key, the required combination is formed and the mechanism opens. A cylinder lock is easier and cheaper to replace, since only the cylinder needs to be replaced, while lever lock requires replacement of the entire mechanism.

There are also electronic and electromagnetic locking mechanisms. Distinctive feature Such locks have a special opening and locking mechanism. In order to open the lock, an electromagnetic pulse is required, which will turn off the magnet. Such options are used in sports clubs, office premises. When opening and closing, the mechanism does not wear out, which ensures its long-lasting operation.

An interesting feature of some electronic locks for plastic doors is that they can transmit information to a computer device about who, when and how many times entered the room. For this purpose, special electronic keys are programmed, the use of which is monitored by the system. This function can be used to find out if an organization's employees are late.

This locking mechanism is compact and an excellent replacement for the conventional mechanical version. A special feature of an electromechanical lock for a plastic door is that it can be opened using an electronic key, a control panel, or a regular key.

What type of lock should I choose?

The choice of a lock for plastic doors is made depending on what goals the consumer is pursuing. The first selection criterion is the size of the lock, which is determined by the type of door into which it will be built. Once the size is determined, you can decide which lock is needed - single-point or multi-point.

A single-point lock for a plastic door is installed in those leaves that separate rooms inside a building where burglary protection is not required and there are no temperature changes. In a situation where a closer is not installed, you should install a door with a latch, additionally selecting a push mechanism.

When installing a closer, you should choose a latch with a roller mechanism so that you do not have to set the closer to make a strong bang when closing the door. Lever handle With this arrangement you won’t need it, a regular one will do. The door will be locked in the closed position thanks to the closer, and not the roller.

A multi-point lock on plastic doors is installed if the door is located between a cold and warm room, and also when it serves as an external door. If the door is not properly pressed, drafts cannot be avoided.

If the door is installed as an external door, maintain subzero temperatures when using a single-lock device, she will not be able to. Ice will accumulate on the lower and upper corners, the pressure at the edges will worsen, but in the center it will remain the same, as a result the canvas will be subject to deformation. With the help of additional trunnions, the multi-locking mechanism will much better press the blade along its entire height.

Installation of locks

Not only is it important right choice lock for a plastic door, but also correct installation. If the installation technology is not followed, problems with the operation of the mechanism will begin and the lock will not perform its main function.

The best solution is to entrust the work to a professional who is well versed in the process, knows the technology for installing locks and the design of a specific mechanism. An ordinary consumer is unlikely to be able to quickly and without practical training master the process of installing a lock for a plastic door, so it is better not to waste energy and nerves and entrust the work to a professional.

As important nuance It should be noted that replacing the lock is not difficult, unlike its installation, which is due to the design features. The procedure can be easily performed independently using a regular screwdriver.

To summarize, it should be noted that the correct choice of a lock for a plastic door depends on the conditions under which it will be used. If the choice is made correctly and the installation is done efficiently, the mechanism will serve long years without breakdowns.

A plastic door is a design that is noticeably different from a regular door. First of all, it's a combination different materials – metal profile and PVC plastic. Secondly, this combination is multi-layered and varies in different areas. The installation of a locking mechanism on this product should be left to professionals: this design has too many nuances.

Door structures made of plastic

The lock on the plastic entrance door should obviously be different from the device for locking the balcony or interior doors. Moreover, this difference is significant and is explained by the design of each model.

The basis of the door leaf is a sandwich panel and a double-glazed window. Essentially this is an option window design, but more rigid, with a heavier frame and not fully glazed, although such options exist. Repairing the product is difficult - due to the multi-layer structure, and repairing the fittings requires special skills. But do-it-yourself adjustment is quite possible.

• The entrance structure is larger in width and weight. The sandwich panel here is much thicker, the frame includes stiffeners, and the double-glazed window is installed in triple glazing to achieve good thermal insulation. Glass can be impact-resistant, which increases the overall level of safety.

This model has limited functions: the sash can be opened in the opening or ventilation mode. The advantage of the product is that the design can be unusual and decorative.

• Interior - the sandwich panel here is much thinner, and the double-glazed window is installed as a single unit. This option is often completely glazed. Operating mode is only opening, as no other functions interior model Not needed. The fittings are handles, hinges, a lock, and special ones are selected here, despite the lightness and thinness of the fabric.

• Balcony – this design is multifunctional. The sash can be opened in ventilation, micro-ventilation, opening, and position fixing modes. It must be equipped with a handle on the balcony side. The design is close to the entrance, since it must provide heat and sound insulation of the home, so the sandwich panel here is thick and the glass unit is triple glazed. In the photo there is a door to the balcony.

In addition, there are sliding, hinged and folding models, for each of which special hinges, handles and locks must be selected.

Locks for plastic doors

Most of the mechanisms are of the mortise type, although there are also overhead models. Their installation is quite complicated, and repairs are also not easy. In addition, it is necessary to take into account the purpose and weight of the sash.

The following mortise locks are most often installed.

• Level - closing is ensured by extending several plates. This method of locking is the most reliable and safe, although it cannot be compared with a multi-point locking method. It is almost impossible to open a plastic door lock with such a device - secret part its very reliable.

• Cylindrical - devices with a cylinder. When locked, the pins are arranged in a certain order in height. Opening is possible only if the pins coincide with the relief of the key. A mortise lock with a cylinder is quite suitable for entrance structure, although not as reliable. But repairing plastic door locks in this case is very simple: you just need to replace the secret mechanism.
• Electric - in this case there is no key, nor is there a handle. You can open the entrance door using a card or key fob. The reliability of the devices is very high, hacking is almost impossible, but without power supply it turns the door into an insurmountable barrier.

• Electromagnetic – the sash is held down by magnets. This is a fairly new mortise device, but it is also reliable. Without power supply the mechanism does not work. Installation is only possible by specialists.
  Multi-point - 2 and 4 points. A multi-point lock for plastic doors includes several elements, allowing you to achieve maximum pressing of the door to the frame, burglary resistance, and durability. Multi-point mechanisms are made of durable of stainless steel. Repairing them is very difficult. However, this modification is more durable. The photo shows a 4-point multi-locking device.

Lock for a plastic balcony door

Its difference is its size. The door to the balcony performs the function of a street door, but at the same time, it enters the living space, and is usually located at a sufficient height, so that, in fact, it does not perform security functions.

Regardless of what the door leaf is made of, it will require the installation of a lock. And if for wooden doors Almost any device is suitable, then for PVC you need to select special locks for plastic doors.

Features of locks on plastic doors

Conventional locks are not suitable for plastic doors. When you try to install it on a canvas made of PVC frame damage will be caused that can render the entire structure unusable. For this type of product, specially designed locking mechanisms are produced.

An important condition is the use mortise device: it allows you to maintain the functionality of the doors without spoiling their appearance. It is possible to use overhead types of locks. Such designs are relevant for high-traffic areas where a mechanical lock will quickly fail due to natural wear and tear.

Models of electromagnetic devices

Locks for plastic doors can be electromagnetic: the main advantage of such a mechanism is its durability. It can increase home security if used in conjunction with an intercom. Such locks also have a number of disadvantages: if there is no power supply, it will turn off, and besides, this model has a fairly high price.

Mount electromagnetic lock possible only in top part doors. The lock will ensure that the door closes tightly, but may deform its leaf over time, especially if they are not made of the same material. quality material. If the frame is deformed, the glass unit may fall out. These problems can be avoided by observing the following conditions:

• Electric locks on plastic doors do not like thermal changes. It is necessary to ensure year-round comfortable temperature work.
• Regularly maintain and check the door closer.
• Check the magnetization of the magnetic device.
• Install a rectifier to combat power surges.

Layout of lock elements

Exists a large number of manufacturers of similar locks, models in which you can get confused. If you want to purchase reliable device, able to last for a long time without the need for regular repairs, we recommend paying attention to SOCA SL-100B. This castle has an attractive appearance, reliable system, the kit includes the equipment necessary for the operation of the device, and installation instructions are included.

Lock installation diagram

The lock for a plastic door SL-180L is considered quite good. It is distinguished by its great power, it can pull up to 180 kg, which allows it to be used in commercial premises, installed on entrance doors. Such devices are produced with different characteristics, you need to pay attention to them. The main parameter when choosing should be residual magnetization: if its indicator is high, such a lock will not be suitable for installation on a plastic door.

Residual magnetization is harmful door leaf, since it does not allow you to open it without effort. This factor increases the load on the structure’s fastenings and can deform them.

Diagram of connecting the lock to the power source. Included with each lock.

Multi-point lock

There are other options for locking mechanisms, for example, a multi-point lock for plastic doors. The main feature of this type of device is the locking mechanism itself. It has at least two points of contact. Such a structure can ensure a tight fit of the door leaf to the frame, and will also significantly protect the room from the penetration of criminals. It is quite difficult to break into such a lock.

The locking blocks are located on a narrow strip, which is fixed to the door leaf. Multi-point locks for plastic doors are produced by Russian and foreign companies. The following models are especially popular:

• Dorseif HV is equipped with four pins, cuts into the canvas, ideal for protection against criminal attacks. Produced this product in Germany, high-quality durable steel is used for its manufacture. The lock can be opened from the outside using a key, and from the inside by pressing the handle.
• ELEMENTIS PZF is an analogue of the above product, but costs less.
• Maxbar MB – multi-point lock for aluminum doors, can be used for plastic products. The difference between it and previous models is the ability to open with a key not only from the outside, but also from the inside. Stainless steel is used to make the case.

Multi-point lock for plastic doors

Electromechanical locks

Door locks for plastic doors can be electromechanical. This is a compact, lightweight mechanism, narrow enough for high-quality insertion. If the door will be opened no more than 200 times a day, this solution will be suitable. By installing this type of lock, you will have the following advantages:

• Various opening options: using a key, electric key, button, remote control.
• The design is more reliable than any mechanical lock and is better resistant to wear and tear.
• The door can be opened and closed quickly.

It is advisable to choose the most compact lock for a plastic door. It is worth paying attention to the crossbar, but it must be thick enough. Experts advise purchasing PROMIX brand products. For example, the Sheriff 5 model is excellent option for installation on a swing plastic door. The model resists temperature changes well, does not rust, and interacts with all types of control devices.

The disadvantage of such a lock is its dependence on power supply. It opens as soon as the power goes out.

Features of the sidebar

You don’t have to think about how to embed a lock into a plastic balcony door if you don’t intend to do it professionally. To mortise locks, you need special equipment, which is unprofitable to buy if you need to service several home doors. It is better to turn to specialists who can do the work accurately, quickly, and inexpensively.
