How to select the door lock?
1. We need to choose a brand with quality assurance. Because brand manufacturers in all parts can supply the after-sales service and free door-to-door maintenance in the warranty period.
2. The door thickness is 35-50mm, which is suitable for spherical locks. The door thickness(plug-in type) is 35-55mm. The mortise door lock thickness is 42mm. The bullet lock thickness is 35-55mm.
3. The center distance: it is necessary to select the lock according to the structure of the door. The length of the lock tongue can be divided into 60mm and 70mm. If the width of the door bone is more than 100mm, 70mm should be selected. It should be 60mm if it is less than 100mm and more than 90mm.
4. Pay attention to choosing the lock in the same opening direction as your doors, because the handle lock is divided into the left handle and right handle.
5. In the selection of handle locks, the handle shape of each functional door lock should be consistent to make the room more harmonious.
6. Hinge: attention should be paid to the selection of hinges with sufficient strength, so as to prevent the door from falling for a long time, which may affect the opening of the lock or even damage it.
How to install the door lock?
1. Special attention should be paid to the installation of spherical door locks. Only the end with safety can be removed, and the end with key must not be removed for installation. It is better to read the manual carefully before installation.
2. Attention should be paid when installing the handle lock: if the left and right opening are exchanged, the handle cannot be lifted when opening the door. Because the middle and high-grade handle locks on the market have the function of exchanging left and right, it is unnecessary to consider the direction of opening the door when purchasing.
3. When installing handle locks and spherical door locks, one to one installation instructions designed by the original factory shall be used.
4. After the door lock is installed, the door lock must be removed when painting, so as to prevent the exposed parts from being stained with paint. When removing the paint, the protective film of the lock will be damaged.
5. During the construction period, in order to protect the door lock, it is not allowed to wrap the exposed parts of the lock with adhesive paper (wrapped with masking paper). Otherwise, the protective film on the surface of the door lock will be damaged after being disassembled.
