More: Oh, the door in the installation of the time, is considered firmly, there are expansion screws fixed, and the tank into the mud, and now demolition of it, this door frame is certainly broken, or else can not be removed - Unless the door around the top of the wall smashed, but this is impossible.

Formal level mark hit the door in the door on the door, it is best to have qualified code (hit the door is false), the level describes the security door, the thickness of the door frame steel. 3. Door lock level: A / B / super B. Super B best. Personally think that the ultra-B-level lock is a must, B-level lock of the national standard anti-technical open (lock tamper of the key indicators) for 5 minutes, ultra B anti-technical open time for 180 minutes. Like the difference between Audi and Alto. Personal recommended Wang Li, the only door made and lock the business, the door is of good quality. All doors are super B locks. The strength of the crystal can see Pan Pan Jing (Pan hope for the B-lock, to recognize), Jingjing also for the super B-class, is the price is too high, the door is still very good.
