1. Select stainless steel doors from manufacturers with quality assurance.
2. Pay attention to the lock that is the same as the opening direction of your door.
3. Pay attention to the width of the door frame of your home. The ball lock and handle lock should not be smaller than 90 mm.
4. Pay special attention when installing the stainless steel door: only the end with the fuse can be removed to install it. Never remove the end with the key. It is best to read the manual carefully.
