A security deadbolt is a special
kind of locking mechanism. This kind of door bolt is a far superior
locking system than any other residential entry door lock. It is
considered to be more secure than an ordinary key-operated lock because
the weight of the locking bar is usually sufficient to increase break-in
time to 10 or 15 minutes. This type of door bolt is widely used in
hotels and industries. A big heavy duty deadbolt on the front door is
sufficient to give us a clue that a home is secure. The security
deadbolt has not only been ingeniously designed to provide the strength
of several door locks, but also has the aesthetics and simplicity of a
single lock.
What is a security deadbolt?
A security deadbolt is a bolt on a lock that is moved by turning the
key or knob without activation of a spring. It is a type of door lock,
when locked, extends a heavy metal projection (or bolt) into the door
jamb. Unlike a spring-bolt where the bolt is held in place only by the
pressure of a spring, and can easily be retracted, a deadbolt lock
cannot be opened unless and until you rotate the lock cylinder.
Deadbolts help in preventing forced entry because they provide atleast
one inch of surface contact between the door and frame. The deadbolt can
be retrofitted onto most entry doors including hollow and wood core
steel doors and many other door locks.
