Rating of the best lever door locks for 2020

The lock on the front door is one of the main elements of the entire structure, because all other security elements built into the door become completely useless if potential burglars can easily open the lock itself.

What is

Recently, almost all entrance doors are equipped with two types of locks: lever and cylindrical. Lever devices are excellent locking mechanisms that have an increased category of strength against attempts to break open the door using force. The lock itself works with the help of special metal plates in which figured holes are cut. It is these plates that are called suvalds, from which the name of the castle comes.

When the lock is closed, the levers fit tightly behind the locking element and do not protect the door from being opened. When the key is turned to open, these plates come out of the slots, and the door opens, rising to the height necessary for opening. The lock is considered with increased secrecy when there are at least 6 such plates. The door will open only when all these plates have taken the correct position.

Due to the fact that the keyhole for such devices is rather large, the lever devices are opened by burglars using lock picks. In order to avoid such an opening, or at least to complicate the tasks of the burglar, manufacturers add special armor plates, plates and similar things to the design.

How it works

The device has a fairly simple design. It consists of a metal body, in which there are levers and crossbars, fused into one piece with the locking shank. It contains a toothed comb, as well as a secret mechanism that allows you to block the opening if an unsuitable key is inserted into the well. This mechanism is made of high-strength steel and a special groove is cut through, which makes the device more secret.

In the comb of the lock, special holes are often made on its teeth, which break one of the main hacking tools - a roll. But the main element of this type of device is precisely the levers. These plates are attached to the shank. And between them there are special plates that keep the levers intact and prevent friction. Some manufacturers put springs on them, which also make it difficult to open them.

How does the mechanism work?

The key inserted into the keyhole rests on the levers, clinging to the slots in the plates with grooves. When turned, he begins to pull them up. If the slots on the levers completely coincide with the notches on the key, then the shank stand will be passed without problems. Then the crossbars begin to move. They keep the door locked. After turning the key, the mechanism returns to its original position.If more than one turn is closed, all movements will be repeated as many times as closed. The more turns you need to make to open, the more difficult it will be for a potential burglar.

Features:

Devices with a lever mechanism can be hinged, mortise or overhead. Some manufacturers produce locks with an electrotechnical mechanism. The most widespread are mortise locks, overhead locks are used somewhat less often. Lever type mortise units can be opened on both sides with a key only. The overhead has a latch and a spinner on the inside, with which you can open or close.

Leveler devices are also called safe. Due to the fact that they are very often installed on safes. A feature of this type of device is that the door of the safe also performs the function of its wall, so it cannot be opened from the inside.

Recently, new product options have begun to appear. Some of them can be recoded, others are carried out in a special case, which can accommodate 2 locks of this type at once. Such products make it possible to recode the mechanism, without replacing the entire mechanism, if the keys are suddenly lost.

What are the features of the key

There are special overlays on the key. It can be one or two beard. In its shape, precisely because of the beards, it resembles a butterfly. It is usually made of brass, much less often a steel key is made. On it along the edges of the barbs there are bulges in as many as the levers are in the device. Each groove pushes a specific lever. The key is made in a rather large size, about 10 cm. The manufacturer is often written on its head.

What to look for when choosing

The main feature that you need to pay attention to when choosing is the material from which the device is made, as well as other parameters:

1. Housing. The side of the device that is directly adjacent to the door must be made of hardened steel. In addition, a special armored pad is used. It is placed in order to drill out the shank was difficult. Even if a burglar has a scheme, opening it is made very difficult, almost impossible, due to the armored plate.
2. Suvaldy. The more there are, the more difficult it is to open such a device. In reliable devices, 6 to 8 levers are installed. Their number can be easily counted from the notches on the key barbs. Each notch corresponds to its own leveler.
3. Rigeli. They are made of strong steel, inside which a special armored rod is installed, making it difficult to cut it. The ledger trim is made of hardened steel to make it difficult to physically knock the door out. The more steel parts there are in the product, the more difficult it is to open the door. Therefore, despite the cost, it makes no sense to save on the lock.
4. Protective shutters of the mechanism. This is a fairly recent invention in the manufacture of locks. If the key is incorrect, the protective shutter will lower when turning and clamp the master key inside, preventing it from going out to either side.

Advantages and disadvantages

Lever type locks have much more pros than cons. The main advantage is considered to be high reliability and difficulty in opening it.

Among the minuses, it can be noted that in most models, you can open the door from both sides only with a key. Therefore, if it is inserted from the inside, it is not possible to open it from the outside. In addition, the disadvantage is that opening, in case the keys have been lost, becomes a very problematic option. Numerous methods of protection practically prevent you from opening a locked door on your own. In this case, it is better to call specialists who can help open the mechanism. The same should be done with an accidentally jammed device, although this, due to its reliability, is extremely rare. But, nevertheless, no one is immune from a possible marriage.That is why, you should only purchase products from trusted brands and not try to save money on safety.

In general, lever locks are reliable and will last a long time, protecting the home from potential burglars.

Currently, the Russian market presents a huge selection of lever locking systems for steel entrance doors. We suggest considering the rating of the most popular models, which was compiled as a result of analyzing customer and user reviews.

Guardian EMZ 1.02

The leader is the locking systems of the Russian manufacturer Guardian, which are made using equipment of Swiss and Japanese production. The overwhelming majority of lever devices have at least 6 levers, forming up to 10,000 different combinations and providing a high degree of protection against burglary using a master key or picking a key. In some series, vertical bolt systems are used, which makes it possible to produce locks with the highest security - more than two billion different combinations.

The EMZ 1.02 model is a hidden-type lever locking system. In normal position, the latches can be easily operated by means of a door handle. The deadbolt is locked by means of an electromagnetic motor. Domestic products Guardian are much cheaper than similar systems of foreign production, despite the high quality, which is confirmed by various certificates and results of technical tests.

CISA 57.655

Slightly inferior to the Guardian brand are the lever locks of the world famous Italian brand CISA. The main feature of Italian locking products is an independent lever system, which was developed and patented by the company's engineers. CISA differs from conventional fixed tooth systems in that the tooth spacing can be changed. As a result, the company was able to bring the number of secret combinations to 244 million, which makes it almost impossible to decrypt the mechanism and copy the keys.

To increase the reliability of locking systems, CISA manufactures pin protection pads, as well as mounting plates with a manganese insert. The cover plate with armor and pin secret combines the advantages of the lever and cylinder devices, becoming another outstanding development of the CISA brand. A cylinder with a shutter is built into the locking system, which can be lowered if the key does not match the pins, thus the key is locked in the keyhole.

The model marked in the rating is a lever locking system. The five-toe ledger is made of galvanized steel. Anti-burglary APLS provides secure blocking and is resistant to hacking attempts by various means.

The lack of symmetry of the sides increases the number of possible combinations many times over.

The company has developed copy-protected My Key locking systems that have become the new security standard. A duplicate can be made only upon presentation of the lock owner's card and the original key. The movable elements, which are located on the axis, interact with the elements inside the lever type mechanism Mottura 52Y771 My Key, make it possible to turn the key, thereby opening / closing it.

Output

Many steel doors are equipped with high-quality lever locks, but this significantly increases the cost, since additional armor plates and plates have to be used for greater protection. Therefore, it is preferable that the locking system combines two mechanisms: the lever mechanism - for protection against burglary with the use of force, cylindrical - against intellectual burglary.
