Degol knowledge  C-level cylinder lock

C-level cylinder lock core principle

The c-class anti-theft door lock core is a new type of technology that adopts multiple anti-theft technologies, a variety of integrated design and production of bullets and blade structures. The c-class anti-theft door lock cylinder is equipped with a side-inward pressing side column bayonet device, which largely eliminates the possibility of violent force opening of the lock. It is the most reliable door lock with anti-theft performance on the market.

Is the c-level lock cylinder better than the b-level lock cylinder ?

Anti-theft locks are divided into three levels: A, B, and super B. The C-class country has not established a standard. The C-class lock cylinders currently on the market are actually super-B blade locks.

In fact, the B-level lock cylinder is flat or crescent-shaped, and there are two rows of concave keyways or cylindrical multi-point concave keyholes on one or both sides. This is the super B level lock cylinder and the C level lock cylinder. The difference! There are different styles, types, grades, brands, etc. of anti-theft locks on the market. The grade can be judged from the surface of the key. The keys of the A-grade anti-theft door locks are parallel, with only single-sided single-row bullet slots, and B-grade anti-theft. The anti-theft performance of the door lock is much higher than that of the A-class anti-theft door lock, with a row of curved and irregular lines on the key surface. The super b-class anti-theft door lock adopts double-row plus curve on the key structure, which has better anti-theft performance. The c-class anti-theft door lock has much more anti-theft performance than the super b-class anti-theft door lock.

Anti-theft door cylinder is basically divided into three levels, namely, A-class, B-class, super B-class. Among them, A-level lock core of the anti-destructive opening time is greater than 15 minutes, anti-technical open time is greater than 1 minute. B-class lock core of the anti-destructive opening time is greater than 30 minutes, anti-technical open time is greater than 5 minutes. And ultra-B-level anti-theft door lock core of the technical opening time is greater than 4 hours.
