Bronenakladka on the cylinder lock: description, device, types and reviews

Each of us strives to maximizeSecure your home from the encroachments of intruders. Interfering with penetration is possible in many ways, but the easiest and at the same time effective is the installation of a metal (or even armored) door. But even in this case, 100% safety can not be guaranteed, because each input group has a weak point - a keyhole.

An experienced thief can crack any lock forminutes, after which the protective structure loses all its useful properties. But if the armored pad is installed on the cylinder lock, then the reliability and breaking resistance of the door will increase noticeably. There remains only one question: how does it protect the keyhole?

Bronenecks

Bronenkladka - a decorative element madeof high-strength and wear-resistant steel, which serves to protect the lock mechanism from the onslaught of vandals or breaking through drilling or pulling out. In its construction, the armored plate has only two moving parts, which is necessary for the key to enter the keyhole. In accordance with this for each mechanism, it is necessary to select an original armored pad.

Bronenakladka on the cylinder lock differs fromof the protective element on the toothing mechanism only by the shape of the cut-out for the key, and also by the presence of rotating parts. Both types are made of high-strength steel with the optimum percentage of carbon, which provides the necessary hardness, strength and at the same time plasticity for protection against impact.

The device of the armor plate

Constructively the armored plate is ametal plate in a shape corresponding to the shape of the lock. Its dimensions are defined in such a way as to provide the best protection for the central part of the mechanism. To protect the core, the design has a special swivel washer with a thickness of up to 6 mm. It is made of chrome-plated steel.

To armor on the cylinder lock increasedthe degree of protection of the apartment, it must fit tightly to it. For this purpose, miniature spacer mechanisms are handled that adjust the height of the lining. In some models, such adjusting screws are missing - the armored plate is attached directly to the lock.

To give an attractive appearance, andalso with the purpose of "inscribing" the element into the design of the door, it is painted with a special anti-corrosive composition for the color of bronze, brass, chromium and other metals. Armored pads can be bought in the store, but it's best to order their manufacture.

Types of armor plates

All types of protective elements are classifiedaccording to the level of protection provided by them. First of all it is necessary to single out separate and separate varieties. Bronenakladka on the cylinder lock has in its design two parts - one of them is installed directly on the keyhole, and the second - under the door handle. Such a system can be called more reliable, since the most vulnerable places are protected separately from each other.

Solid overlays are a monolithicA plate in which the cut-outs for the handle and the core of the lock are made. On the one hand, it is less reliable (an attacker can try to pick up a pad at the door handle), but on the other - significantly increases the time required for breaking.

Bronenkladki can also be divided into mortise and invoice according to the installation technology. Each installation method has its own characteristics and requires separate consideration.

Overhead armored plates

Presented protective pads have a lowreliability and resistance to mechanical impact - with the proper desire, an attacker can simply knock down such a design. The thing is that the installation of the armored door on the cylinder lock is carried out from the outside of the door.

It is superimposed on the locking device andPresses against the metal surface with bolts that are inserted from the inside of the door. If the screws are sufficiently tightened, the lining will cut into the steel sheet and will look like a cast protective element. But in practice, something like this is not always possible.

Mortise armored plates

Embedded armored pads consist of twoplates. One of them is fixed from the outside of the door structure directly to the keyhole, and the second one is installed from the inside. The tightening screws connect both plates to a single system, which is why it is impossible to wrest it. The only drawback, which has a cutting armor plate on the cylinder lock, is the price. Its value can reach 10 thousand rubles.

The type of overlays presented can be mounted in thethe design of the door at the time of its manufacture. In this case, the structure can be attached to the lock itself or buried in an armored sheet of metal. This method of installation significantly increases the resistance to burglary.

Bronenkladki with a magnetic mechanism

Bronenkovka with a magnetic mechanism -innovative technology to protect the locking mechanism. In their design there is a special protective cap. Completely blocks the access to the core of this armored pad on the cylinder lock. Protection increases, not only from breaking, but also from the onslaught of vandals - to pour glue into the hole or to put matches there will not work.

To open a lock protected by thisconstruction, it is necessary to have a special magnetic code of secrecy, which is usually built into the master keys. Magnetic armored pads prefer to buy to protect street doors.

Rules for choosing armored plates

To properly choose a bronenagluku,It is necessary to find out the diameter and length of the protruding part of the lock (if the lock is not built into the door). When selecting the elements, you should pay attention to the material of manufacture. It is better if it is high-carbon steel, coated with anti-corrosion compounds. In addition, the armored door to the cylinder lock must match the color of the door. Bronze, chrome, steel are common shades that fit into any design.

In order not to get lost in a huge assortment,pay attention to the world's leading manufacturers. These include Disec, Kale, Mottura, Rezident. The products of these manufacturers are made of high-strength carbon steel, which can not be drilled. Even the overhead design will increase the resistance level by an order of magnitude.

But special attention is paid to the armor plateCisa on the cylinder lock from the Italian manufacturer. Protective fittings are made of cemented nitrided steel, has a unique design and has no vulnerabilities.
