| How does one select the type of bullet resistant door and frame product that is suitable for the project? |
Bullet resistant doors are subject to the criteria established in the UL
752 document "Standard for Safety for Bullet Resisting Equipment". Eight
distinct "levels" of bullet resistance are established ranging from a small
.38 handgun (Level I) through to a 7.62 high powered military assault rifle
(Level VIII). When selecting an Ambico bullet resistant door and frame do so
with reference to the anticipated threat - please refer to
Table One. If you are uncertain about your choice
ask one of our professional salespeople for advice or e-mail us with your
query. Note: Levels 1-3 are handguns.

| The door must be very heavy. Do I need special hardware with a bullet resistant door? |
Ambico bullet resistant doors weigh approximately fourteen pounds per square foot and operate with readily available heavy weight builders hardware. We recommend that the lockset should be factory supplied. Ambico has developed bullet resistent hardware to complement the bullet resistant ratings of our doors and door frames.
|
| Can bullet resistant doors and frames be supplied with bullet resistant glazing? |
| Yes - bullet resistant glass, acrylics and plastics are available and may be factory pre-installed. The bullet resistant capacity of the door, frame and glass must be complementary. |
