Home security is most important
these days and dead locks are pre-eminenet for security of a home or a
business firm. Dead bolt locks are supposed to offer the best
protection, and hence should be used on all exterior doors. You have to
be sure that the locks you use have bolts that extend at least one inch
into the wall, and that the locks are made of solid metal with no
exposed exterior screws. Some dead bolt locks are also available with
free-spinning collars which prevent intruders from removing the cylinder
with a wrench or vice grips. It is called "dead" because there
are no springs to operate the bolt. The lock is only operated manually
with a key or a thumb turn from the inside.
Types of Dead Bolt Locks
- Single cylinder lock: Single cylinder locks operate with
a key from the outside and a thumb lever on the inside.
- Double cylinder lock: Double cylinder locks use a key
both inside and out. These locks offer better protection. For
instance, if a burglar enters the house through a window, he cannot
open the door without a key. Double cylinder locks can also pose a
fire safety hazard, so you must consider your options and choose the
best solution for your home.
- Vertical dead bolt: This is another lock option. These
locks are used primarily to secure double doors. The vertical dead
bolt lock is secured to its mating plate with pins that make it
difficult to pry. Vertical dead bolts are also available in single
or double cylinder models. Dead bolt locks must be locked when you
leave your home. If you pull your door shut and walk away, the door
is not locked.
