Common questions
What does the DS 78mm drive do?
Part 9761001 is the Somfy drive wheel for a 78mm round DS tube. It fits on the output end of the motor and locks into the tube, so the motor turns the roller without slipping.
Which motors does it fit?
Somfy lists more than 100 compatible motors across the LT50 and LT60 ranges, including Sonesse, Altus RTS, Oximo RTS, Maestria RTS, Orea RTS and Sunea motors, plus Somfy T5 and DMI5 operators.
What application is it built for?
Somfy lists this drive for rolling shutters that use a 78mm round tube. It has a black finish and carries a 5 year Somfy warranty.
What else do I need with the drive?
Pair it with the matching DS 78mm round crown (9707027) at the motor head. The DS 78 LT50 Set (9012239) bundles this drive and that crown under one part number.
What if my tube is a different size?
The store carries LT50 crown and drive sets for 60mm octagonal (9012233), 70mm octagonal (9012234) and 2.5 in round (9012231) tube, along with the LT50 2.5 in Hard Clip Drive (9206019). Match the drive to your tube profile.
