Selection of locks:
1. Selection of lock cylinder
When selecting the lock cylinder, we should first make sure whether the lock we need to install is in the field or indoors. If it is the former, we should choose more than six lock cylinders, and the safety index should be higher. If it is indoor, we can choose less than six lock cylinders, maybe the coin slot lock without a bullet, Because the room is not locked when we close the door, some even can not lock, so the general installation of a simple lock cylinder can be.
2. Selection of lock body
Generally, the door lock for entering a house is a multi method lock tongue. The main purpose is to improve the anti-theft, anti impact and anti blocking function. If it is indoor, the single tongue or double tongue lock body can be selected.
3. Door lock handle
If the door lock device is completed, it will feel very laborious when closing the door, that is, the gap between the door leaf and the door frame can not adhere to certain rules, beyond which the door leaves will be squeezed tightly. Perhaps the size of the door leaf and the door frame is not the same, so we must make clear when shopping for locks.
