Description
These doors and glass are designed and manufactured to retrofit into existing steel buck door frames. They are rated at Level 4 resistance PLUS they they have been certified by the Underwriters Laboratories (UL) as fire resistant up to 2,ooo degrees Fahrenheit for 45 minutes.
To most bullet proof manufacturers and laminators, Level 4 is the hardest nut to crack. In terms of material advancements, many modern bullet resistant barriers see little difference between three shots from a 9mm pistol (i.e., Level 3 security) and 5 shots from an Uzi or M16 (Levels 6 and 7). But Level 4 barriers must stop a .30 caliber round. Popular in hunting and some military sniping, these bullets are large chunks of lead optimized for long-distance accuracy, speed, and impact.
The simple material challenge of passing a Level 4 test is further complicated in the case of a door, which has moving parts and unavoidable liabilities at the hinge, jamb, knob, and lock. The hardware delivered are bullet resistant, as well.
Designed and built and assembled in the USA
