In an emergency, e.g. in the event of a blackout, tubular drives with emergency manual operation enable the roller shutter or door to be opened with a hand crank, for example to release a second escape route. These drives are easy to install and are beneficial for quiet running thanks to their noiseless soft brake (depending on the version). Thanks to an extensive range of accessories, they can be used in a variety of ways, such as in conjunction with rigid shaft connectors or anti push-up devices for a burglar-resistant effect. Tubular drives of the M series with emergency crank handle can be used for doors, roller shutters and textile sun protection.
