Anonymous users2024-01-24Three questions: First of all, let's look at the figure below for installation, which is very simple.
The second question is the price: A-grade B-grade ordinary marbles (single-row and double-row) 30-80; Super B grade marble + curve groove (60-150).
Super B grade, single-sided internal groove milling (single-sided blade) 100-200 Super B grade, double-sided internal milling groove 200-500
The third problem is safety (arranged from low to high) single-row marbles, double-row marbles, marbles + curve grooves, single-sided blades, double-sided blades, and idling double-sided blades.
I recommend a Saidian brand super B-class C-level idling blade anti-riot lock cylinder supervised by the expert committee of China's lock industry, which is anti-tin foil, anti-technology opening, anti-interruption, anti-prying, and the quality is very good. As shown below:

The best anti-theft performance is the super B-level anti-theft lock cylinder, which is a super B-level lock cylinder that is interacted with a single row of bead marbles, slider marbles, suspended marbles and double rollers, which has the advantages of low mutual opening rate, strong anti-pulling performance, anti-technology opening, anti-theft with keys, anti-prying and anti-drilling opening. But no matter which kind of smart anti-theft lock you buy, the lock cylinder is generally copper. There are also different types of lock cylinders, and the lock cylinders that are more commonly used at present are European-style lock cylinders.
Copper lock cylinders can be bought within 50 yuan of retail sales.
