 The
National Locksmith Testing Lab, recently did
a series of
comprehensive examinations on deadbolts and door knobs that not
only proved informative, but also fun. First, the stars of this article consist of the
hardware used
on the door that weathered our violent attacks. The surviving
hardware consisted of the following:
1. The new Schlage B660P series of deadbolts that have a
beefier bolt assembly and stronger holding screws than that of
the standard 400 and 100 series. 2. A MAG High Security Box Strike (Which states on the box
that it will stop kick-ins it does and should be used with
all deadbolts). 3. A Don-Jo classic wrap around door reinforcer that fits on
the door under the deadbolt and door knob to stop the door from
splitting it does, too. These three items can be seen in Photograph
1. And while they appear a little abused, they did work.
So well, in fact, that despite the assault the deadbolt still
operated.

deadbolt, the MAG 747 Heavy Duty Strike, and the Don-Jo
door plate.

The
doors and framing construction used for the test were standard
for residential applications. The rough frame was built to
standard residential construction, except the header, which
played little part in a security installation, using building
grade 2x4. The doors were standard residential steel clad doors
with wood rails or edges.
On
the first door I installed a ŗFaultless˛ deadbolt and door
knob purchased from a local Builderšs Square store.
In
the package the $12 deadbolt was nicely displayed and it
certainly looked good, at least to the uninformed public.
Photograph
2,
shows the installed Faultless door knob and deadbolt. The good
looks are only skin deep. The tools used in the torture test was
limited to those any homeowner or burglar would have around.
After only a couple of hits with the hammer, the deadbolt was
moved downward exposing the inner workings (see Photograph
3.)

3. The first assault was a hammer attack on the
Faultless deadbolt.
|
At this
point, the deadbolt is actually circumvented and compromised.
This took about five seconds and two blows of the hammer. Photograph
4, shows our thug sticking a screwdriver into the hole to
pull the bolt back.
|

4. A couple of quick blows provided an opening large
enough to reach in and to open the deadbolt.
|
Despite
being able to open the door rather easily and quickly, we went a
little further. Photograph 5, shows
what happened after using the screwdriver and hammer to beat on
the deadbolt a little longer. Still, it was decided not to open
the door in this manner. Instead, I selected brute force, I got
to kick the door open (I have always wanted to do this).
|

5. Next came a simple screw driver attack. The lock was
easily ripped off the door.
|
Backing
up a little, I leaned back and gently kicked the locked door. It
literally sprung open. The strike went flying as my size 13-1/2
shoe lightly touched the deadbolt. The
deadbolt strike screws functioned to help split the door frame,
and that was all (see Photograph 6).
|

6. The kick-in - Easy! And the door remnants - good fire
wood.
|
Now
we proceed on to the real test, the reinforced door and strike
plate.
The old
battered door was removed and a new one rehung. After truing the
door with shim stock, it was drilled and the guard plate was
installed on the door.
The
reinforcement plate was also installed in the jamb. Photograph
7, shows the Schlage B600 series deadbolt being installed
on the door. Photograph 8, shows
the MAG 747 strike installed with two cover screws and two
strike screws located on the inside of the box itself. All four
screws are 2˛ in length giving excellent penetration of the
jamb and frame (see Photograph 9).
The
Don-Jo wrap around plate was then installed along with the
deadbolt and a doorknob. For the next test we locked and
attacked the door knob. As expected, the knob was circumvented
with a pipe wrench in about eight seconds (see Photograph
10). After twisting the doorknob open with the wrench, it
was hammered off. This was adding insult to injury. Nothing was
really accomplished, except to prove the non-protective feature
of the average door knob during a force attack.
|

10. Using a wrench on the door knob posed little
challenge.
|
The real
test followed. The deadbolt was beat for about two minutes with
the claw hammer. The results? Despite the marring and a few
indentations, there is no circumvention here as before (see Photograph
11).
|

11. Battered but not defeated. Even after repeated
hammer blows there is no defeat.
|
This
deadbolt is designed with a bolt cover or guard and is seated
into the face bore hole, preventing the lock from being knocked
out of place. Even if a small opening was made, the bolt cover
does not allow access to the bolt.
The
Don-Jo wrap around plate added further protection by not
allowing the hammer to pierce the sheet metal of the door,
allowing the lock to loosen or be exposed. The Don-Jo wrap
around and the Schlage B600 withstood the first in a series of
assaults.
Not
succeeding at knocking the lock off the door, it was then
attacked with a screwdriver and hammer. This attack resulted in
an unsuccessful attempt to punch the lock cylinder through the
back of the lock resulted (see Photograph
12.)
|

12. Trying to knock the cylinder out the back of the
lock didnšt work either.
|
Photograph
13,
shows an attack with a pry bar. This had no effect on the
security of the door, except to bend, mar, and disfigure the
installation. It was now time to again, kick the door in.
|

13. Pry Bar attack - No Good.
|
The first
kick was at the same force as that used earlier on the
non-reinforced door with the Faultless deadbolt and knob.
Despite a level 4 reading on the Richter Kick Scale, nothing
happened.
The kick
force was increased to a level 7. While the door didnšt move, a
couple of the supports for the door broke free. Nothing like
having the house come down around the door!
After
replacing the door supports, the door was given one last
gigantic, all-out effort kick, (level 9). Still, NO results. Not
wanting to miss out on any of the self-abuse, several others in
the testing lab added their own kicks, but none were so great as
a 300 pound locksmith/safecracker could give.
One
torture tester backed up 20 feet and rushed the door yelling, ŗI
have steel toed boots on.˛ He jumped up and kicked the door
with a Karate kick that would have crushed most any door.
Nothing happened.
Then he
turned around and backed up 30 feet.
He
concentrated, focused, and like a professional athlete he
approached the door at warp speed, jumped, and gave that
deadbolt a double diabolical Shudo-Kahn death kick.
Again,
the door withstood the competent attack that a lesser prepared
door would have easily acquiesced to (see Photograph
14).
|

14. The kicking attack after reinforcement of the door.
|
Unsuccessful,
a strange smile crossed this torture testers frustrated face,
slightly reminiscent of the Grinch before he burgled Who
Village. Vaulting to a nearby YALE forklift, he stated that it
was time for the door to DIE.
Not
wanting to crush the wall of the Testing Lab,
he
decided not to ram the door, and instead placed the forklift
blades up against the door, putting gradual pressure against our
reinforced locking system (see Photograph
15).
|

15. Man the battering rams and full speed ahead!
|
Once
touching the door, he stepped on the gas.
The
wheels started turning, but the door and its hardware held.
After increasing the speed, the door still did not open (see Photograph
16). At maximum speed the wheels burned through the floor
tile and into the cement. Suddenly, and finally, the door
crashed open.
|

16. With wheels spinning, the door and its hardware
withheld the forklift assault (not considered a UL
standard).
|
The
result! The strike plate split, the frame was slightly cracked
and, except for two large dents from the forklift blades, the
door remained unscathed (see Photograph 17).
An incredible display of what some rather inexpensive additions
to a deadbolt installation can do.
|

17. To think it took a forklift at full speed to open
this door.
|
After
viewing the damage, it was evident that the eventual strike box
failure was due to the extensive twisting and bowing of both the
door jamb and the framework. In a home, drywall and other wall
components may make for an even more rigid framework, better
supporting the strike, and making the entry even harder!
So, while
the forklift assault has not yet been added to the UL Standards
Test, The National Locksmith Test Lab and demolition crew has
provided you iron clad proof that you are safer when using the
right equipment. These products really do work!
The
products used in this test are just a sampling of available
products that can greatly increase door security. For more
information consult with a professional locksmith in your area.
