Super B lock

- Mar 08, 2019-

The key shape is a single-sided blade inner milling slot or an outer milling slot key, and the lock cylinder type is a side cylinder lock cylinder. After the Ministry of Public Security detected 270 minutes, the technology could not be opened, and the regional mutual opening rate was zero. The structure of the marble is locked by the double-row blade and the V-shaped side column. If the lock cylinder is opened with a strong twisting tool, the internal core of the lock cylinder is broken, and the self-explosion is locked, resulting in failure to open.
