You donβt even need to look at crime statistics to know that one of the most popular is apartment thefts. That is why any owner of real estate is trying to resolve the issue of ensuring the reliability of his front door. Often, housekeeping specialists enter the apartment or cottage through the door - this is not once confirmed by them in numerous interviews. To exclude any attempt of unauthorized access to the apartment, you can use steel doors with modern locks. Let's talk about what you need to pay attention to when choosing a castle. And the most popular products among buyers are door locks with a handle for entrance doors.
Types of door locks with handle
All the huge number of market offers can be divided into several groups. There are only three of these groups - these are mortise locks, patch and padlock mechanisms.
If you approach the choice of the castle from the point of view of reliability, then among these types of devices the most reliable, according to criminologists, is a mortise lock. They should be considered first of all - they are able to provide a sufficient level of security for door structures.
You can purchase other types of locks, but only as additional protection systems.
About choosing locks
When choosing such an important part as a lock, it is recommended to pay attention to such factors as the quality of materials, type of construction, level of privacy, manufacturer.
If it became necessary to install a door lock with a handle, then the first thing to decide is what the purpose of such a purchase is, and how to use this lock to ensure a sufficient level of security of the room.
For example, if the dwelling is located on the first floors, then the castle mechanism must be arranged in such a way that it cannot be opened from the inside. So, even if a thief enters the room through a balcony or a window, he will not be able to quickly open the door and will not 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 a steel door, a mortise door lock with a handle was chosen, it will in no way spoil the aesthetic condition of the door. This mechanism will be hidden inside the door - this further increases the burglar resistance of the structure. Opening this mechanism quickly will not be so easy, and time is the main and very valuable resource for apartment thieves.
Padlock and padlock mechanism
Padlocks and padlocks are much less reliable. For a professional with an arsenal of equipment, the opening process will take several minutes. In addition, these mechanisms can significantly disrupt the appearance.
The device of locks with a handle, types
According to the type of mechanism, a door lock with a handle is divided into several types. These are level locks, cylinder, disk and biometric systems. Consider the advantages and disadvantages of each castle.
Level castle
This system is characterized in that the secret part consists of several separate plates - together they form a highly reliable, crack-resistant mechanism. For maximum protection, the plates work together with curly cuts, which are then combined with the grooves of the key during opening.
Such a door lock with a handle has a fairly simple mechanism, but it is a reliable choice. There is one minus of these mechanisms - for such a lock, a large well is made in the door, which is very convenient for working with master 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 already much more difficult for an attacker to get the master key into the desired groove. Yes, and a set of master keys for such locks is an expensive pleasure, and there are less and less professionals who skillfully cope with the quiet opening of such systems.
Modern locks with handles are equipped with a special master key recognition system. In addition, the mechanism is protected from force hacking methods. If an outsider tries to somehow open the device, the lock will simply lock - it will be impossible to open it even for the owner of the house, however, the property will remain intact. Many decide to purchase such a mortise door lock with a handle. The price of the simplest model is from 5000 rubles.
Mortise Lock
From the name of these mechanisms, it becomes clear that the cylinder acts as the main element. Turning this cylinder with a key unlocks the lock.
These solutions are often used in homes, but they are not as reliable as level locks. Design - lock, handle with a key. Professional crackers and forensic scientists believe that such doors can be easily opened. To do this, the specialist screws a red-hot screw-screw into the working part of the mechanism, 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 such locks there will be no problems - the design of the product is quite simple. The market offers different types of solutions in terms of price and reliability. Choosing such a lock system for the front door, you should not purchase the most expensive mechanism - even despite the assurances of the manufacturers, using a red-hot self-tapping screw, this system is opened in 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 internal doors, a door latch is better.
Disc lock
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 simple. The handle allows you to protect the lock from the use of master keys - here you need a special tool, since the well has a complex shape. But you can open the mechanism with the help of physical force and an electric hand tool, however, this causes a lot of noise, and apartment thieves try not to create excess noise.
Mounting Features
The mortise door lock with a handle can be easily installed with your own hands. For installation, a well of suitable size is required. Such locks can be installed in any type of door.
If the installation is carried out by fixing the strip on the end of the door leaf, this significantly reduces the level of reliability of the door block. It becomes more vulnerable to physical impact.
During installation work, holes are drilled for the mechanism on the end of the door. With the help of a grinder, a slot is cut under the keyhole. When all the openings 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, a lock cylinder is installed - the system already has a hole for this. It remains only to install the handle and check the operability - the door latch should slam shut well, and the mechanism - close-open.
Market offers
Such locks are now produced by companies such as Barrier, Guardian, Elbor and others. For example, Guardian models provide a completely reliable mortise door lock with a handle. Its price is from 5000 rubles and above, depending on the level of reliability.
In general, mortise locks for metal and other types of doors are a good choice. They do not spoil the aesthetics of the door leaf and at the same time have protective functions.
