Points to note when using door locks

1. In the daily use of door locks, it is best to hold the handle and screw the deadbolt into the lock body, make sure the door is closed, and then let go. Do not hit the door with force, otherwise it will reduce the service life of the lock.
2. After using for a period of time, the lock may not be unlocked smoothly. You can use the special lubricating oil provided to drip into the lock cylinder, and open it several times. Do not drip ordinary lubricating oil or oil into the lock core.
3. Do not use a damp cloth to wipe the lock body and handle. Some metal locks will rust, and alloy locks will wear off the coating, which greatly reduces the aesthetics.
4. It is very important to choose the door lock, and the installation is even more important. Be sure to install the door lock correctly, and don't be too casual.

What is the door lock?

The door lock is an important safety piece. The door lock consists of two parts, one part is fixed to the door and the other part is fixed to the body, the door is prevented from opening outwards by the door latch, and they are disengaged by a simple lever movement or the action of pressing a button. The door lock must work reliably and will not disengage itself under a certain impact force.

Enhancing Door Lock Security: Additional Measures to Consider

While a quality door lock forms the foundation of security, additional measures can further strengthen the protective measures. These may include reinforcing the door frame, using security plates or strike plates, installing a peephole or video doorbell, and implementing a security system with surveillance cameras and alarms. These supplementary measures work in tandem with the door lock, creating multiple layers of defense and acting as deterrents against potential intruders.

Advantages of glass door locks

As the name suggests, the glass door lock is installed on the glass door. The advantage of the glass door lock is that the glass does not need to be opened, and the safety performance is good. The glass door lock material is usually made of high-strength structural steel or zinc alloy die-casting or stainless steel, which overcomes the shortcomings of iron and zinc alloys that are easy to rust, age, and lack rigidity.
