Locks, Bolts And Keys For Your Home
August 15, 2008 | Leave a Comment
Most security experts agree that a
single outer door lock will not provide adequate protection. For
example, any tumbler-type lock with an opening for a key also
provides an opening large enough for the lock to be picked. Thus, a
combination of two different types of locks are recommended. Here
are the most common types of locks used in the home:
Spring Latch Locks: A popular and
convenient lock that snaps closed whenever the bevelled latch seats
into a striker plate is the spring-latch lock. However, this lock
can be easily forced by inserting through the door frame a thin blade
or stiff plastic between the latch and the strike plate. Thus, a
spring lock should always be augmented by a second lock of a
different type.
Dead Bolt Locks: The dead bolt lock
features a solid, rectangular latch that forms a bolt between the
door frame and the door itself. This lock is difficult to force or
jimmy and is a good choice as an auxiliary to any other key lock.
It’s available for either key operation or manual interior knob.
Barrel-Type Bolt: A barrel-type bolt
serves the same function as the dead-bolt lock but is restricted to
manual, interior operation only. It may be used with an inxpensive
night-latch, and it is difficult to force if it’s well made and
installed properly.
Chain Locks: Used as a supplementary
interior lock, the welded chain offers a valuable security feature.
It permits the user to open a door partially to exchange letters,
messages, or small parcels without completely unlocking the door.
For proper mounting, the slide should be installed just above and
slanting toward the chain.
Remember, if you have taken possession
of a new home or apartment , you should immediately change the
pin-tumbler locks on all exterior doors. A registered locksmith can
usually alter the previous combination.
