CSTR 11 LOCK & NON-LOCK ASSEMBLY

A lock is a mechanical or electronic fastening device that is released by a physical object (such as a key, keycard, fingerprint, RFID card, security token, coin etc.), by supplying secret information (such as a number or letter permutation or password), or by a combination thereof or only being able to be opened from one side such as a door chain.

A lock may also be a clamp or a stop designed to prevent the flow of a liquid or the motion of a caster or wheel

Parts of a lock assembly include a cylinder or lock body, where a key is inserted. When locked, the cylinder engages a series of spring-loaded pins that keep the cylinder from turning. When a key is inserted, the uneven edge pushes the pins upward to fit the key’s height in that location within the lock body. Essentially, it recognizes the correct key when the pins move into their proper places. This “opens” the cylinder, allowing the bolt to move, and you to open the lock. The lock engages a piece of metal or plastic that extends from the door into the receiver and holds it closed. In addition, a lock assembly may include mounting components, brackets, washers and bolts.
