2. How to choose a hardware door lock?

When choosing a door lock, you should pay attention to the following aspects.

(1) When choosing door lock products of famous brands, it is necessary to see whether the outer layer of the lock body of the door lock is smooth and clean, and whether there are defects that affect the appearance.

(2) Care should be taken to select a lock that opens in the same direction as the door. Insert the key into the hole of the lock cylinder to open the door lock to see if the opening is smooth and sensitive.

(3) Pay attention to the width of the door frame. The door frame that can install the ball lock and the handle lock should not be less than 90cm. You can turn the door lock handle and knob to see if it is easy to open.

(4) Usually door locks are suitable for doors with a thickness of 35-45mm, and some hardware door locks can even be used for doors with a thickness of 50mm. The length of the door lock tongue should not be too short.

(5) Some handle locks are divided into left-hand and right-hand, so pay attention when purchasing. The way to distinguish whether the handle lock is left-handed or right-handed is very simple: stand on the outside of the door facing the door, the door hinge on the right hand is the right hand door, and the left hand is the left hand door.
