    According to the national standards, the Class A door must be locked with Class B, but it is not clear that it is Super Class B (because Class B is not recognized by the national standard, and the relevant national standards only recognize Class A and Class B), especially the requirements of the current standard are alternative, good and bad, so this must not be answered. But if you send a picture, you should be able to judge.

Directly change the anti-theft door of Wang Li Teneng to lock, automatic anti-locking, which is different from the locks of other brands equipped with national manufacturers on the market. You can go to the store to see, the shape of the lock body, the lock cylinder, and the shape of the key are not ordinary. This is a proper super C-class.
