Raynor FireCurtain™ fire-rated rolling counter shutters are the standard for facilities that require a listed fire counter shutter in a rated fire wall. Provided with fusible links that automatically release to close the door at 165°F, the shutter can also be triggered by smoke and heat detectors, a building’s alarm system, or SS90 fail-safe devices. All FireCurtain counter shutters comply with UL, C-UL, FM and CSFM requirements for 3-hour, 1 1/2 hour and 3/4 hour fire rating. Optional UL-labeled countertops are also available. When safety and fire protection are crucial, choose FireCurtain fire-rated rolling counter shutters.
