Mortise lock for a wooden door: reliable protection of an apartment from burglary

Door locks have varying degrees of security. There are several types of such devices, which differ in principle of operation and installation option. A mortise lock for a wooden door is a very common device. For its installation, a special socket is prepared inside the canvas. The closed location of such a lock does not spoil the appearance of the door and makes it invulnerable to damage.

A mortise door lock is the best way to protect against burglary

What does the installation of a mortise lock for the front door give?

These devices differ in the installation option. Mortise models can be mounted in a niche, which is made in the side of the doorway. There is another way to install such a lock, in which it is located on the back of the door. In this case, a special pad is used.

Mortise locks are mounted in the door leaf and do not spoil its appearance

Many people believe that installing a flush model negatively affects the strength of the door. However, this assumption is not true, since the size of the device does not exceed 30% of the total thickness of the web. Thus, there is still quite a lot of solid material (25-30 mm). Some wooden doors are very durable. The most reliable are products made of oak. Installing a mortise lock in this type of wooden door does not weaken it in any way.

Such devices have many advantages that are worth paying attention to. For example, the closed location of these devices increases their safety. In this case, it is much more difficult to get to the larva and locking elements (crossbars). This location of the castle prevents it from getting dirty. An important advantage is that such devices do not spoil the appearance of the door. This is especially true for those doors that are sheathed on the back with an additional layer of wood.

Note! Mortise locks for wooden doors increase their durability. This is due to the fact that their body, located inside the canvas, acts as an armature.

Mortise locks provide safety and reliable protection of the apartment

Like any other device, flush-mounted models have some drawbacks.The main one is the fact that when the lock fails, most often it becomes necessary to replace the sash.

Cylinder mortise door locks: their features

All mortise devices are divided into 2 groups depending on the principle of operation: cylinder and lever. The first option is quite common among domestic consumers. Many experts point out that such devices are not considered the best. The doors on which the cylinder mechanism is installed are rather difficult to open with a lock pick, but they are not reliable.

The principle of operation of such a mortise lock for an entrance door is that several cylinders are located inside the mechanism. They are at different heights, so it is extremely difficult to open this mechanism with a pick. In case of incorrect arrangement of cylinders lock jammed.

The principle of operation of the cylinder mortise lock mechanism

Such devices have one weak point - their larva. Several strong, localized blows will knock the mechanism out of the door. Today you can solve this problem by purchasing additional protection. Only cylinder locks include a larva. There are two common options for additional protection for these devices:

• overlays;
• balloons.

The pads are used in order to exclude the possibility of knocking out the lock. In turn, the balls are located inside the mechanism and prevent the device from being removed from the door with a drill.

Currently, you can find many companies that produce such devices. Bulat cylinder mortise locks are very popular. This is due to their democratic value. A mechanism of this type can be purchased for only 400-800 rubles.

In order to increase the degree of protection of cylinder locks, balls and linings are used

Cylinder locks are very easy to use, which is their advantage. In case of loss of keys, it is not necessary to completely change the mechanism. You can simply insert another core. Thus, this type of lock is a good option for an entrance door made of wood. When buying a mortise cylindrical mechanism, it is recommended to take care of its additional protection.

What is a lock cylinder: description of the code part

The larva is the main mechanism of the mortise device. It is found only in cylindrical locks. The design of this part is quite simple: inside there are metal split rods that are attached to the springs. Their function is to prevent the lock from rotating if the wrong key is used. The larva is present not only in the entrance devices, but also in the mortise locks for wooden interior doors.

Helpful information! If the correct key is used, the following happens: when the rods are lifted, their connectors are aligned with the core. This position affects the movement of the bolt. The recesses on the key body play a very important role. When the combination matches, the bolt is unlocked.

The larvae differ in different degrees of protection and are only in cylinder locks

In addition to the core, the locking structure of the mortise door lock includes crossbars. These parts, in fact, are bolts with the help of which the door leaf is closed.

It is important to remember that the design of the larva can have different degrees of protection. As a rule, most of the options on the modern market do not have high safety performance. Before purchasing a lock, it is recommended to consult with a specialist in this matter, who will tell you which device is best for your case.

Lever mortise locks: advantages and disadvantages of the mechanism

This type of locks also belongs to the category of mortise locks.The advantages of lever mechanisms include a high strength indicator and a long service life. It is these devices that are recommended by specialists because they are able to provide good security.

Previously, lever locks were used to protect offices, and they were also installed in banking institutions. Nowadays, they can increasingly be found in the front doors of ordinary residential apartments. Lever devices, like cylinder devices, can have a handle. When buying a mortise lock with a handle, you need to find out if it fits in its appearance to the door leaf.

The main advantages of lever locks are strength and durability.

The key feature of such a device is the presence of levers. These parts lock the door when the key is turned. Experts advise purchasing locks that have 6 to 8 of these elements. This provides the best protection. The cost of such devices is higher than the price of cylinder analogs. For example, a mortise lock Guardian of the suvald type costs in the range from 700 to 1200 rubles.

The lever mechanism is almost impossible to break with physical effort. It is shock resistant making it a great option for protecting your front door. It is also worth noting that such devices can be supplemented with armored plates, and this increases the degree of their protection several times.

However, this mechanism also has some disadvantages. The main disadvantage is that the keys for lever locks are large in size. Therefore, they are not very convenient to carry with you. Opening and closing of the lock is performed on both sides of the door with only a key, which can also be counted as negative points.

Mortise lock for wooden door: combined type

Many experts recommend just such devices for protecting the front door. Combined models include two types of mechanisms. Today you can find double locks that have the same principle of operation and devices with different opening options. The most common locks are:

Combined mortise locks include two types of mechanism

• two-cylinder;
• two-lever;
• lever-cylinder.

Note! You can distinguish ordinary devices from combined ones by one sign - the size of the mortise lock. In this case, its dimensions will be much larger than standard models.

It is important to remember that in such a device, both mechanisms can be independent. However, most often they complement each other, which is the preferred option. This is due to the fact that when the first mechanism is opened, the second is simply closed.

Of the disadvantages of such devices, it is worth noting that they are quite difficult to repair in case of breakdown. They are distinguished by high strength and long service life. Therefore, the repair of the mortise lock may not be necessary for many years. In any case, the choice of the device depends entirely on the personal preferences of the owners.

Combined locks can be double-lever, double-cylinder or double-cylinder

As an alternative to combination locks, two separate products can be installed. Mounting the cylinder and lever device on the door greatly increases the degree of protection of the living space.

1 class. Devices that belong to this group are distinguished by their simplicity of execution. Most often, they include crossbar mechanisms, which are the least reliable of all. Breaking of such a lock is done in a matter of minutes, so it is not recommended to install it on the front doors.

Mortise door locks divided into four safety classes

Helpful information! Mortise locks for wooden doors with or without a handle are not class 1 security.

Grade 2. In this case, the degree of protection is slightly higher, since it will take an experienced burglar longer to open the door without a key. Such locks are not the best, but they are suitable to protect the premises from penetration.

Grade 3. Locks that belong to this group can serve as reliable protection against burglary. They are characterized by increased strength and safety. The break-in time for such a device is approximately 20 minutes, which is a rather long period.

4th grade. Most reliable devices. However, the price of this type of mortise lock is quite high. To break into such a device, you must have a set of special tools at hand. The time it takes to open the door where the class 4 product is installed is 30-35 minutes.

Rules for the selection of mortise devices (entrance and interior)

Before buying a mortise mechanism, you need to study several rules that allow you to choose the most suitable device for a particular case. Features of choice include the study of installation nuances and consideration of the type of door.

A very important point is the purpose of the mortise mechanism (where exactly it will be installed). Mortise locks for interior doors, as a rule, have a slightly different design. Therefore, before purchasing a device, be sure to inform the seller about what the device will be intended for.

Entrance doors can be left-handed and right-handed, based on this it is necessary to select a lock

Devices used in doors that are located between rooms are often devoid of a secret mechanism. In this case, a conventional latch is used, which is quite enough to close the interior sheet. A mortise lock with a latch is cheaper than full-fledged counterparts that are mounted on front doors.

It is important to remember that when choosing a locking device, it is necessary to build on the thickness of the door. This is very important, since when buying a device that is too bulky, it may turn out that it simply does not fit in this indicator. It is quite simple to determine the optimal model: its thickness should not exceed 70% of that of the sash.

Note! Before purchasing a mortise mechanism, ask the seller about the warranty. Devices that do not have it are most often of poor quality.

As a rule, there is no secret mechanism in locks for interior doors.

All entrance doors differ in opening options. According to this criterion, they are divided into left-sided and right-sided. Before purchasing a mortise product, ask the seller about which door it is suitable for. Ignoring this rule can lead to the fact that it will not be possible to cut the lock into a wooden door.

And, finally, when choosing a suitable lock with a handle, you must definitely pay attention to whether it matches the door leaf in its design and color. Compliance with the above rules will allow you to purchase a quality model that will serve you for many years.

It is important to remember that the section of the drill must be equal to the thickness of the plunger body. Next, you need to prepare a special device - a jigsaw. Using it, you need to cut a furrow between the two holes.
