Which door lock is best for metal-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. A lock for a plastic door is 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 There are mortise and overhead. Mortise mechanisms are predominantly used, which do not spoil 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 differ from their analogues in their small 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 It is recommended to install a burglar alarm in apartments from “window makers”.

Manufacturers of locks for plastic doors

On Russian market The most common locks from these 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 of the Chinese manufacturer are 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. The products are made from high-strength materials that are not subject to corrosion. All devices have a high class of burglary protection.

The Russian company Guardian produces a wider range of locks for plastic doors. Average cost one product costs 550 rubles. The manufactured products are certified. Model range 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. Even a person without experience can perform this operation 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:

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;

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

Multi-point lock

Due to the complexity of the device and high precision When installing, it is not recommended to install the lock yourself.

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 castle is unique in its own way and has high degree protection. For long-term and uninterrupted operation of the device, it is recommended to purchase locks from the most well-known manufacturers.

Reading time: 8 minutes.

The latch is a mandatory element of the balcony door fittings made of PVC profile. For home handyman will useful information about its purpose, classification and operating principle of each type. Tips from the practice of using balcony latches will also be useful.

Purpose of the latch

The plastic door latch is a very useful, convenient and functional part of a modern door hardware. The simple principle of operation, similar to the operation of the latches on the doors of kitchen cabinets, allows you not to be distracted by monitoring the position of the door. The latch mechanism is designed for the door to be opened freely by a person (if necessary) without applying any serious effort. But at the same time closed position the door leaf is not disturbed by strong gusts of wind. Keeping the plastic door from swinging open while the door lock mechanism is in the unlocked position is the main task of the installed latch.

Another, household name for the mechanism is the smoker’s latch. The explanation for this is simple: just slam the door shut and the smoke will no longer be drawn into the living space; Tightly closing the balcony door with a lock is not required for a short visit to the balcony or loggia. If you use a one-way lock (its handle is located on the side of the room) and there is no latch, the door cannot be closed when exiting to the balcony. So, the usefulness and necessity of installing a latch on balcony door obvious.

Types of door latches

The main difference between the latches used is in the locking mechanism. Based on this feature, the following types are distinguished:

Subsidence of the door leaf, its distortion, or changes in the geometry of the frame structure can disrupt or make it impossible for the roller and latch to function properly. The working latch (in the form of a roller or beveled tongue) must fit exactly into the striker clamp mounted on the frame. Emergency adjustment consists of adjusting the door leaf using the fittings screws. During the setup process, the position of the door relative to the frame opening is adjusted. In this case, the leaf can be raised, lowered, shifted to the right or left, its top or bottom, and adjusted the force of pressing the sash to be opened to the frame. If this adjustment does not help to establish correct work latches (in general, this is very rare) - you will have to dismantle and reinstall one of the parts of the mechanism. Usually they move it in the desired direction and attach the bar with the groove.

The magnetic latch does not create problems in this regard. When the initial installation is verified, it is correct and reliable operation will not change from a slight distortion or sagging of the door.

Installing the magnetic latch takes a few minutes

Another characteristic difference between latches. If the halyard and roller ones close with a characteristic click, then the magnetic ones hardly disturb others.

Due to the fact that the functional elements of the latches are attached to the end part of the frame and door profile, they are not visible from any viewing angle. This feature helps to preserve the strict classical aesthetics of not only the door, but also the entire structure installed in the opening.

Caring for all types of latches is very simple. Periodically, their mechanisms are wiped from dust, dirt, debris and lubricated (except for the magnetic latch plates) special means for window fittings. Any silicone grease or regular machine oil (spindle). The main thing is to be sure that the one you are using lubricant composition Resins, acids and other aggressive substances are not included.

External handle

Handle - plastic petal

To close, or rather pull, the door from the street side, it is necessary to provide a special external handle. Made of metal, more often of durable plastic, the handle visually resembles a shell or petal in shape. A plastic shell is much more tactile, especially in cold season. But it is easier to break if used carelessly, and the material itself has a tendency to break down with prolonged exposure sun rays, negative temperatures and others external factors. The main advantages of a more expensive metal handle are resistance to mechanical stress and long term operation. Typically, the outer door pull handle is located at the same height as the lock's rotary handle. This position for closing the door is very convenient.

You can do without an external shell handle only if the door lock mechanism is double-sided, that is, internal and external rotary handles of the lock are required.

Double-sided handle for a plastic door

The choice of external handles in specialized companies and construction supermarkets allows you to choose a copy with a convenient ergonomic shape and the desired color.

At self-installation, when replacing latches, it is advisable to use screws: no shorter than 30-35 mm– for fastening the roller cylinder with a safety margin; no longer than 19 mm– when installing an external handle (this ensures that the screw will not reach and damage the glass unit during installation or further exploitation pens).

Latch Installation

When starting work, you need to be sure that in the near future its position relative to the frame opening will not change. If necessary, you will have to independently set the position of the door leaf and the pressing force against the frame when closing it with the rotary handle. Screws will help with this door hinges. Now let's move on to the main installation. A screwdriver or a more convenient screwdriver will be enough; for marking, take a pencil.

The easiest way is to install a magnetic latch. No special setup or precise installation is required. Both strips are simply attached at the same level - to the end of the door and the frame profile. Small offset relative position will not interfere with the proper operation of the latch.

Opposite the latch, make a mark with a pencil and attach the striker in the center of the groove.

Another thing is with the roller and halyard latch mechanism. In both cases, the exact position of the bar with the groove relative to the latch is required. Without doubts and measurements we fix it in seat balcony sash latch itself. Opposite its center, we draw a line with a pencil and draw this line outward so that it is noticeable when closed door. Having closed the door, we mark a similar mark at the same level, but on the frame. At this height the center of the grip of the strike plate should be located. Now we fix the bar with the lock along the mark with one screw and check the correct operation of the mating elements. If the result is negative, the bar is shifted and the functionality is checked again. If further adjustment is not required, the bar is secured with a second screw.

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 on different areas different. 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.

Most often the following are installed mortise locks.

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 - the secret part is 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 the entrance structure, although it is not so 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 stainless steel. Repairing them is very difficult. However, it is this modification that 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.

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 special size housing, which corresponds to 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 an attractive and aesthetic appearance 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 of the door to the canvas. 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 locks in question for plastic doors are equipped with a standard type cylinder 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 a lever lock requires replacing 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. With this arrangement, you won’t need a push handle; 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 cold and warm room, and also when it performs external functions. 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’s better not to waste your 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 for many years without breakdowns.

Hide

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, but 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. If you try to install it on a PVC canvas, the frame will be damaged, which can render the entire structure unusable. For this type of product, specially designed locking mechanisms are produced.

An important condition is the use of a mortise device: it allows you to maintain the functionality of the doors without damaging them 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.

An electromagnetic lock can only be installed in the upper part of the door. 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 operating temperatures.
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

There are a large number of manufacturers of similar locks and models that can get confusing. 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, as 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. These products are manufactured in Germany and are manufactured using high-quality durable steel. 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.
