Breaching Technologies Shotgun Hinge Breachign Door - Manual (Page 8)

Door Breaching
The BTI Shotgun Breaching Door has been designed to provide realistic training utilizing
low cost blanks, birdshot, or game loads. More costly frangible ammo (AVON type) can
be utilized if desired. Due to safety reasons, buckshot, steel shot and slugs are not
recommended due to the increased potential for ricochets.
For increased safety and door longevity, we recommend using BTI Frangible Shotgun
Training Rounds on your new Shotgun Door. When used properly, all of the material in
the round disintegrates on impact and eliminates virtually all splash-back and ricochet.
Caution
Rounds fired during the breaching operation may damage nearby property and
personnel in the line of fire. The door has been designed to promote the glancing
impact of rounds on the structural members, and as a result, ricochets of rounds
away from the trainee are highly likely. If you are unsure of your mounting
methods and location, please consult a professional.
Lock/Knob Panels
The BTI Shotgun door contains features that
require the trainee to locate shots in the
proper place to effectively breach the door.
When the lock/knob panels are inserted into
the structure, the tab of the panel (simulating
the bolt of the lock or door knob) is not
exposed. This forces the trainee to properly
place the shot at a location that would sever
the tab (bolt in real situations). Improperly
placed shots with this product, as in real
situations, will not sever the bolt, resulting
in a failed breach. An example of a properly
aligned shot is seen to the right.
Hinge Panels
Similarly the hinge panels require the
proper location of shots to fully fracture and
clear the door for entry. The grooved
hinges will fracture after a single shot made
in the top, bottom, or center of the hinge
panel. The solid hinge panels often require
two shots to yield; one shot in the top of the
hinge and one shot in the bottom. An
example of a center shot on a grooved hinge
is depicted at the right.
