Deadbolt's

A dead bolt or dead lock (also deadbolt), is a locking mechanism distinct from a spring-bolt lock because a deadbolt cannot be moved to the open position except by rotating the lock deadbolt. The more common spring-bolt lock uses a spring to hold the bolt in place, allowing retraction by applying force to the bolt itself. A deadbolt can therefore make a door more resistant to entry without the correct key.

A deadbolt is often used to complement a spring-bolt lock on an entry door to a building.

      

Types of deadbolt's

A deadlock may be either single deadbolt or double deadbolt. A single deadbolt deadlock will accept a key on one side of the lock, but be operated by a twist knob on the other side. Double deadbolt locks will accept a key on both sides and can therefore do away with the twist knob. This prevents unwanted unlocking of the door by forced access to the interior twist knob, via a nearby window for example.^[2]

A variant of the standard deadbolt is the vertical deadbolt, which generally rests on top of a door. Vertical deadbolts resist jimmying, in which an intruder inserts a pry bar between the door and the frame and attempts to pry the bolt out of the jamb.

Other types of deadbolts include:

• Single deadbolt with removable thumbturn
• Classroom Function (thumbturn only unlocks door)
• Exit Only Function (no external deadbolt)
• Pushbutton Deadbolt (mechanical or electrical)
