- Due to door selection
When choosing a lock, first of all, you should pay attention to choose a lock that is consistent with the opening direction of your own door, so that the door can be opened and closed more conveniently. Secondly, we should pay attention to the width of the door frame. In general, the spherical lock and the handle lock cannot be installed on the door less than 90mm. If the width of the door frame is more than 90mm and less than 100mm, the ordinary spherical lock 60mm tongue should be selected. For locks larger than 100mm, a 70mm lock tongue can be used. In addition, whether the thickness of the door matches the lock is also an important option.

In terms of listening to the sound, the copper door lock is mostly solid during the opening process, so the sound is not dull, and the stainless steel door lock sounds crisp.
