"It is widely known among law enforcement and Crime Prevention
professionals that the area around the door strike is normally
the weakest part of the door assembly. Most lock manufacturers
supply a very small strike plate which does not allow much
reinforcement of the door frame area.This is complicated by the
fact that only very short screws, normally 3/4 of an inch in length,
are furnished with which to secure the strike plate to the door frame.

This weakness is often enhanced by the fact that the strike plate
has an opening to accommodate the latch which is larger than the
latch itself. This is done by the manufacturer to allow for
misaligned or warped doors, or other issues that for whatever reason
does not allow the latch to line up squarely with the strike plate.
This feature therefore allows the door latch to have some "play"
within the strike plate, often allowing the door to move slightly
back and forth. Any reinforcement of the strike plate area by a
larger plate, longer screws or incorporation of a feature to minimize
the "play" in this larger opening will help to make any door more secure.

There are a variety of after-market products that address some or all
of these issues. Sure-Strike is one such product. It increases the
surface area of the strike plate itself with a larger surface than the
one normally supplied with a lock assembly, thereby adding strength to
the facing of the door. At the same time, longer screws are provided
with which to secure it to the facing, thus securing the strike not only
to the door facing but into the walls studs as well. Further, the patented
feature within the mechanism itself addresses the issue of misaligned doors.
It allows the door latch to engage the strike, while simultaneously
eliminating the "play" in the latch/strike mating. This provides for an
all-around stronger, and therefore safer, assembly.

As with anything related to crime or criminal activity, there are no guarantees
that any lock, strike or combination thereof will successfully prevent a break-in.
Anything made by man can be defeated by man. However, everything a homeowner
does to address known security issues should help to make their home or
business more secure."
