MU-22

Safety Considerations for Motorized
Commercial and Industrial Doors:

Large commercial doors have special safety considerations that should be taken into account as a part of the overall door safety system. A qualified professional door installation company can provide you with the peace of mind you need to assure your motorized industrial door system is safe and in good working order.

Model #MU22 is designed for use on 2 inch thick doors and are custom manufactured to required length. Our Sensing Edges are designed to provide a safe means of stopping and reversing a door’s motion. Typically powered by just 24 volts, electrically activated Sensing Edges are attached to the leading edge of the door. When touch activated, the internal sensor sends a signal to the motor to stop and/or reverse motion.

How It Works

Common installations for the MU extra large Sensing Edges can be found in warehouses and manufacturing plants.
