Door and window locks
First, we should choose products with high reputation, stable quality and good after-sales service.
Second, first check whether the logo and logo of the purchased product are complete (including the product's implementation standards, grades, manufacturer's name, address, production date). Whether the package is firm, the contents of the manual are consistent with the product, and the caution is exaggerated. Does not match the facts.
Third, observe the appearance quality of the product, including the lock head, the lock body, the lock tongue, the handle and the cover plate parts and related accessories are complete, whether the surface color of the plated parts and the painted parts is bright and uniform, with or without rust and oxidation. Signs and damage.
Fourth, repeatedly open, see the sensitivity of the lock core spring. Once the key is lost or the door and window locks fail, it is hard to twist, which destroys the lock and destroys the door. I don't know, the door lock can be easily removed and replaced with the unlocking piece.
