There are some issues to be aware of when installing the door handles to avoid re-rework due to installation errors.
1. The door handle is mounted vertically on the upper corner of the door panel or vertically in front of the door panel to open the door.
2. After the door handle is installed, you need to test whether it can be used. Whether the key can open smoothly, turn the door handle to see if it can rotate.
Regarding the height standard of the door handle, I believe everyone knows. If the conditions permit, the height of the door handle at home can be designed according to the average height of the family, making the home more comfortable.
