Selection method of locks

We should choose copper core, but some of them are plastic, and only a layer of copper skin is wrapped at the head of the core.
The appearance of all copper nickel plating and iron nickel plating is almost the same, but the price difference is very large. Generally, all copper nickel plating is with mute, and iron nickel plating Is without mute. All copper nickel plating is fine, and iron nickel plating is rough.
When the ball type is installed, if the eccentric core is not installed in place, it is very easy to go wrong.
Now the fastest selling is the handle lock. The ball lock is out of date.
The lower the sound when turning the gadget, the better.
The shape of the key must be higher than that of the original key pit.
The more square head tongues, the better the safety.
Enterprise products with high popularity, stable quality and good after-sales service shall be selected.
First, check whether the marks of the product packaging are complete (including executive standard, grade, enterprise name, address and production date), whether the packaging is firm, and whether the instructions are consistent with the product.
Observe whether the lock head, lock body, lock tongue, handle, cladding parts and relevant supporting parts are complete, whether the surface color of electroplated parts and painted parts is bright and uniform, and whether there are signs of rust, oxidation and damage.
Check whether the use function of the product is reliable and flexible, and select more than two for comparison.
When purchasing two-way lock products, all keys must be used to test the internal and external lock.
The insurance condition of the product shall also be checked. It is recommended to try each lock at least three times.
Select trinkets according to the use environment, such as dry and wet, door structure, thickness, left or right opening, door opening or external opening.
Try to choose the lock with more key teeth, because the more key teeth, the greater the difference, and the lower the mutual opening rate of the lock.
