Hardware has great use experts to teach you to buy door locks

Hardware has great use, so don't ignore it because it's small. Seeing locks, hinges, slides, handles, hanging wheels, nails, plate brackets, door stoppers, clothes hooks, bumping beads, touch cards, board pins, etc. have begun to feel deeply "interlaced like a mountain."

Door lock: A penny is a piece of goods, the lock is most afraid of rust and can not be used.

The Taoist Road: Copper-plated nickel and iron-plated nickel can be distinguished. It is recommended to choose a slightly more expensive copper core lock when buying, and do not buy inferior core locks. As long as you carefully select, you can distinguish it by listening carefully. Usually, the copper lock is silent, the iron lock is silent, the copper lock is fine, and the iron lock is rough.

Experts teach the road: buy locks to pick up a large number of locks. The mutual opening ratio is the ratio of the lock and the key. The less the number of keys hit, the stronger the safety and reliability of the lock. When purchasing, consumers should try to choose a lock with a large number of key teeth. Because the more the number of teeth of the key, the greater the difference, the lower the mutual opening rate of the lock.
