The safety of family life is the first, and the performance of the anti-theft door lock core is very important to us. There are many kinds of super b-class lock cylinders on the market, and the super b-class lock core is the best, which has become a topic of concern to many people. Next, Xiaobian will come to discuss this topic of great concern with everyone.
Definition of super b-class lock cylinder
The Super B-class lock cylinder is monitored by the relevant department and cannot be turned on by technology, or the technology is turned on for more than 270 minutes. It should be noted that “Super B Level†is an enterprise standard and not an international standard.
Super b-class lock core which is best
1. Brand products have generally been recognized by many users and have a good reputation and service system. So which is the best b-class lock cylinder, we must first choose from the top ten brands of super b-class lock core.
2, buy a lock to see the "teeth" of the key. The more teeth, the deeper the teeth, the more complicated the arrangement, the more difficult it is to open, and the better the anti-theft performance.
3, pick the lock on the pound said two, one than the weight two to see the lock core. The heavier the weight, the better the quality of the lock cylinder. The more beads in the lock cylinder, the better the anti-theft function.
4, choose the lock core to see the color, look at the work than the color. The quality of the lock cylinder is electroplated, the surface is smooth and the color is bright. Among them, the color is dark yellow, the copper core is relatively strong, the anti-theft performance is better, the color of the lock core is dim, the color is gray and the bubble is zinc alloy, and the anti-theft performance is general.
5. The key rotation is inserted into the lock cylinder. The anti-theft performance of the card is poor. After the key is half-inserted, use 5 to 7 minutes to rotate clockwise or counterclockwise and continue to press the key into the lock. The key of the card indicates that the lock core has poor anti-theft performance. The instructions for inserting the lock cylinder smoothly in the semi-rotation state are good.
