UL 752 Level 3
Bullet Resistance
Krieger’s industry-leading forced entry (FE) double doors with a bullet rating are tested to the new SD-STD-01.01 Forced Entry and Ballistic Resistance Standard—and exceeded the 15-minute test twice.
The UL 752 Level 3 bullet rating means the door can stop 3-shot clusters from a handgun such as a .44 Magnum.
