How to select qualitative doors lock.
The first type of door locks is considered the most reliable. Its design is clear even to buyers absolutely not expert in mechanics. The zapornaja component part of the clasp - levers - fixes a door in shut position. The more in a doors lock of such component parts, the more impregnably it for passe-partouts and breaking. The key from such clasp is massive also has a small beard with cuts of various depth. The door lock too sometimes reaches considerable width that can complicate its installation at a ready door. But it is its almost unique lack.
Cylinder clasps contain the built in core of a cylindricity (in use has the name "larva"). The larva contains about six levers that does its steady against selection of passe-partouts. But for mechanical stability (from beating, twisting and other external damages) such door locks are necessary for strengthening. For this purpose use steel sheets from an outer end of a door and special battening plates - from an underside. As a core of door locks try to make of the strongest metals and alloys.
