How about a Class C anti theft door lock

Strictly speaking, there is no C-level anti-theft door lock at present, this is my experience of doing so many years of locks, because the country has not yet stipulated the definition of C-level anti-theft locks, so there is strictly no, only A, B two-level, but some of the lock cylinder is better to distinguish the ordinary locks to develop a better C-level lock, and a lot of publicity, only to cause the current situation, no matter what level in fact, only to look at two kinds, one is brand awareness, which is a core of the lock, the other is to see the product quality and workmanship, That's the basics. If you don't know, then with so much of my experience as a lock, you can only rely on luck, for example, when you meet me... Dear, you've earned it.

Check it out on my profile. Authentic and effective.

So far, the national standard on the lock cylinder is limited to two kinds of A and B grades, super B grade lock cylinder is the enterprise standard proposed by the lock manufacturer itself, as for the C level or C above the anti-theft door lock, it is also an enterprise standard, the country is not C level anti-theft definition.

As for the C-level anti-theft door lock marked on the market, it is also a higher anti-theft level, and the lock cylinder is also a relatively safe type of anti-theft door lock.

The national standard anti-theft door lock cylinder is divided into Class A, Class B and Super Class B according to the structure

Class A: The key is flat or crescent type, with a row of concave key slots on one or both sides or a cross type with convex key slots on all sides;

Class B: The key is flat or crescent type, with two rows of concave key slots or cylindrical multi-point concave key holes on one or both sides;

Super B grade: the key is flat type, with two rows of concave and S-shaped key slots on one or both sides, or double snake key slots inside and outside.

Anti-theft effect. Household door locks are generally divided into three levels:

1: Grade A, with the technology turned on for more than 1 minute as the qualification standard.

2: Level B, with the technology turned on for more than 5 minutes as the qualification standard.

Three: super B-level, the lock cylinder is monitored by the relevant departments to the technology can not be opened or the technology is opened for more than 270 minutes as the standard. There are many types of super B-grade lock cylinders on the market.

It is best to use a super B-level lock cylinder, generally there are countermeasures under the policy, the anti-theft door can be a good person, and the anti-thief is just a question of how long it takes for the thief to successfully unlock the lock, and it is difficult to use a long time.

They are all anti-gentlemen and not villains.
