More Information
Summary:The device is an articulated cam with an at least partially rotatable cam arm for mounting a vertical traveling industrial door, constructed from a series of hinged solid panels, to a guide track. The cam arm has a threshold force required for rotation as the cam arm includes a dimple which is engaged by a spring-biased nipple. When this threshold force occurs due to impact on the door, the cam arm rotates and the articulated cam and the door break away from the guide track.
