Door lock with handle: types, installation, reliability

You do not even need to look at the crime statistics to know that one of the most popular is burglary. That is why any owner of real estate is trying to resolve the issue of ensuring the security of its front door. Often, house-workers enter the apartment or cottage through the door - this has been repeatedly confirmed by them in numerous interviews. To exclude any attempt to unauthorized access to the apartment, you can use steel doors with modern locks. Let's talk about what to look for when choosing a lock. And the most popular products among buyers are door locks with a handle for entrance doors.

Types of door locks with handle

All a huge number of market offers can be divided into several groups. These groups are only three - mortise locks, overhead and hinged mechanisms.

If you approach the choice of a lock in terms of reliability, then among these types of devices, the most reliable, in the opinion of forensicists, is a mortise lock. They should be considered first of all - they are able to provide a sufficient level of security of door structures.

You can purchase other types of locks, but only as additional protection systems.

About the choice of locks

When choosing such an important detail as a lock, it is recommended to pay attention to such factors as the quality of materials, the type of construction, the level of secrecy, the manufacturer.

If there is a need to install a door lock with a handle, the first thing to do is decide what the purpose of this purchase is, and how with this lock you can ensure a sufficient level of security of the room.

For example, if the dwelling is on the ground floors, then the lock mechanism must be arranged in such a way that it can not be opened from the inside. So, even if a thief enters the room through a balcony or window, he can not quickly open the door and leave the apartment through the door - in this case he will not take anything voluminous.

If, in order to increase the level of reliability of the steel door, the door lock was chosen with a handle, it will not in any way damage the aesthetic state of the door dense. This mechanism will be hidden inside the door - this further increases the burglar resistance of the structure. Open such a mechanism will not be so easy, and time is the main and very valuable resource for apartment thieves.

Suspended and overhead locking mechanism

Hinged and overhead locks are much less reliable. With a professional with an arsenal of equipment, the autopsy process will take several minutes. In addition, these mechanisms can significantly disrupt the appearance.

Locking device with handle, types

By type of mechanism, the door lock with a handle is divided into several types. These are the lock locks, cylinder, disk and biometric systems. Consider the advantages and disadvantages of each castle.

Locked door

This system is distinguished by the fact that the secret part represents several separate plates - all together they form a highly reliable, burglary-resistant mechanism. For maximum protection, the plates work together with the cutouts, which are then aligned with the grooves of the key during the opening process.

Such a door lock with a handle has a fairly simple mechanism, however it is a reliable choice. The minus of these mechanisms is the same - for such a lock a large hole is made in the door, which is very convenient for working with skeleton keys. But manufacturers are constantly working on this, and today the mortise lock is equipped with additional protective systems. Thanks to this additional protection, it is much more difficult for an attacker to get a master key into the correct slot. Yes, and a set of skeleton keys for such locks is an expensive pleasure, and professionals who skillfully cope with the quiet opening of such systems, less and less.

Modern locks with handles are equipped with a special pick-and-pick system. In addition, the mechanism is protected from forcible methods of hacking. When trying to unauthorize somehow open the device the lock is simply blocked - it will be impossible to open even the owner of the dwelling, but the property will remain intact. Many decide to purchase such a lock with a door mortise with a handle. The price of the simplest model is from 5000 rubles.

Cylinder Mortise Lock

From the names of these mechanisms it becomes clear that the cylinder is the main element. Turning this cylinder with a key leads to the opening of the lock.

These solutions are often used in homes, but they are not as reliable as lock locks. The design is a lock, a handle with a key. Professional burglars and forensic experts believe that such doors can be easily opened. To do this, a specialist screws into the working part of the mechanism a self-tapping screw, and then simply pulls out the core.

But, despite this, such a door lock with a handle still has a level of reliability. When used with similar locks there will be no problem - the design of the product is quite simple. The market offers different types of solutions for price and level of reliability. Choosing such a lock system for the entrance door, it is not necessary to purchase the most expensive mechanism - even despite the manufacturers' assurances, this system is opened with less than 2 minutes without noise. These locks do not provide the proper level of protection.

Often, such locks can often be found in office doors, in some apartments and even in interior doors. However, for interior doors, a door latch is best.

Lock type

These solutions are in no way connected with modern entrance doors. Systems of this type function by turning the complete key. The mechanism of these mortise products is also very simple. The handle allows you to protect the lock from using skeleton keys - here you need a special tool, since the well has a complex shape. But the mechanism can be opened with the help of physical strength and an electric hand tool, but this causes a lot of noise, and apartment thieves try not to create excessive noise.

Mounting Features

If the installation is carried out by fixing the bar on the end part of the door leaf, this significantly reduces the level of reliability of the door unit. He becomes more vulnerable to physical abuse.

During the installation work, holes are drilled for the mechanism on the end part of the door. With the help of a bulgarian cut slot for the keyhole. When all the holes on the door are ready, you can install the lock itself - it is installed in the finished slot on the end of the blade and screwed with screws or complete screws. Next, install the lock cylinder - the system already has an opening for this. It remains only to install the pen and check the operability - the door latch should close well, and the mechanism - close-open.
