Common questions

What is the DS 78 LT60 Crown?

Somfy describes part 9705341 as an LT60 crown for EDS 78 tube. It slides onto the motor head and centers the motor inside the tube, so the roller turns true.

Which motors does it fit?

Somfy lists LT60 motors: the 660R2, 680R2 and 6100R2 in CMO, Altus RTS and SJTW versions. This store carries the Altus RTS 660R2 (1162271), Altus RTS 680R2 (1164261), Altus RTS 6100R2 (1166289), 680R2 CMO (1164013) and 6100R2 CMO (1166016).

What is it used for?

Somfy lists it for rolling shutters. The crown supports the head end of an LT60 motor inside a DS 78 roller tube, while the drive wheel on the output shaft turns the tube.

What else do I need?

You need a drive wheel for the same DS 78 tube on the motor's output shaft. The Somfy DS78MM Drive (9761001) fits LT50 and LT60 motors in DS 78mm tube.

Which crown fits 70mm octagonal tube?

For 70mm octagonal tube on an LT60 motor, use the 70mm Octagonal LT60 Crown (9705340). Somfy also sells it with its matching drive as the 70mm Octagonal LT60 Set (9012247).
