Timer roll-down protection TA-4-RD

A roll-off protection functions as a normal bearing, on the other side of the roller shutter shaft than where the tube motor is mounted. If something in or on the tube motor fails, the Roller shutter will unwind at high speed, the roll-off protection intervenes and will block the Axle/Shaft, bringing the Roller shutter to a stop.
