Krieger’s industry-leading forced entry (FE)
hybrid door features a trio of special purpose performance—FE, bullet, and acoustical protection.
First, it is 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.
Plus, it provides an STC 50 acoustical rating
for sound control.
