Working as the frame of the shutter system, rails attach to the wall, guiding the shutter curtain in and out of the box housing. Smaller rails provide a lower visual impact. Larger rails offer more security and resistance to curtain pullout.
For enhanced security, Rollac offers the End Retention System, which utilizes rails with a separate channel that accepts specially designed sidelocks. This system actually locks the shutter curtain and the rail together, providing much greater resistance to force being applied to the shutter via impact..
