Everyone knows that the key part of the lock is the lock cylinder. A security lock with a poor quality lock cylinder is simply ineffective. Therefore, the lock industry has spared no effort in the development and research of the lock cylinder. Now there are super b-class lock cylinders and c-class lock cores on the market. It is said that there are certain differences in anti-theft performance. Then let's take a look at the difference between the super b-class lock cylinder and the c-class lock cylinder.
Let us first talk about the classification of the lock cylinder:
The lock cylinder is the part used to control the opening of the lock and is the core part of the lock. Usually people think that the lock cylinder has A, B, C three-level lock cylinder, but in fact it is not the case. According to the provisions of GA/T73-1994 "Mechanical anti-theft lock": the anti-theft lock is divided into three levels: A, B, and super B. The C-class countries have not yet set standards. The C-class locks currently on the market are actually super B-class. Blade locks, C-class locks should be the concept of enterprise customization. However, the super-B lock and the so-called C-class lock must meet the basic requirements of the national B-class lock, that is, the super-B lock and the C-class lock can be regarded as the B-level lock.
That is to say, the C-class lock is just a kind of folk, it is actually a super-B lock, which belongs to the B-class lock category, but the anti-theft performance is much stronger than the B-level lock.
The following specifically describes the characteristics of these three lock cylinders:
Ordinary A-class lock cylinder: Generally, the security door installed 10 years ago is a class A lock cylinder, the key is flat, also called a word lock, only double-sided single-row bullet slot. In the anti-theft performance, if you unlock it, it will take about two or three minutes to open, and the familiar hand is faster.
Class B lock cylinder: It is a double-sided double-row bullet slot from the key, which is a safer class B. If you unlock the skilled worker, it takes about 5-20 minutes to open.
Super B-class lock cylinder: This is a relatively safe grade. From the key, it is generally double-sided double-row with inner milling slot, and there is a blade or curve next to it. This type of lock core can reach 270 minutes, which is skilled. It takes about 2 hours for the veteran.
However, according to statistics, more than 50% of users are still using Class A locks. Although some Class A locks have multi-layer turns to increase the safety of the locks, there are more turns, and Class A locks are in the hands of thieves. It can still be successfully cracked in tens of seconds, calling on consumers to replace the safer B-class lock core in time.
Afterwards, I will introduce the matter of changing the lock core:
First of all, the lock cylinder upgrade does not need to change the whole door, just replace the lock cylinder. The consumer can disassemble the lock cylinder by himself and purchase the higher-level lock cylinder according to the specifications of the lock cylinder. Generally, the regular security door can replace the lock cylinder.
Confirm the lock cylinder specifications before replacing. There are many types of anti-theft locks on the market. The standards are not the same. Consumers should pay attention to the model specifications of the anti-theft locks and replace them one-to-one. Generally, the B-class lock cylinder and the ordinary lock cylinder have the same shape and installation dimensions. However, there are also special anti-theft door locks, the specifications are not uniform, please confirm the lock core specifications before purchasing.
Read the above about the difference between the super b-class lock core and the c-class lock core. Do you have any doubts about the super b-class lock core and the c-class lock core? In short, with or without c-class locks, the super-b-class lock cylinders are now quite reliable. Under normal circumstances, they can bring room safety to everyone. Of course, if you have a c-class lock standard, it is also the gospel of consumers.
