Our one-of-a-kind rolling curtain shutter has been tested and labeled to UL 10B for 90 minutes with hose stream and UL 1784 smoke & draft. Unparalleled in the market, it is designed to protect openings in any wall rated up to 2 hours – including Fire Walls and Fire Barrier Walls! A simple but unique configuration of textile layers are permanently joined together as one unit and stored on a barrel in the head box. When deployed, the D400 descends as if it were a rolling steel door!
