Feel of touching lock

- Mar 10, 2019-

The feel of the safety door lock is determined by the spring, and the quality of the spring determines the feel and service life when used. Some lock springs are not good, so it is easy to cause the handle to sag, thereby ending the life of the door lock. When you buy, you should try the toughness of the door lock spring. The feel of a good spring is very soft, not too soft or too hard.
