Common questions
What is in the Octagonal LT50 70mm Crown and Drive Set?
Part 9012234 includes a crown and a drive wheel sized for 70mm octagonal roller tube. Together they form the connection between a Somfy LT50 motor and the tube, with the crown centering the motor and the drive turning the tube.
Which motors does it fit?
It fits Somfy 50mm-class 500 Series motors in the LT50 family, including LT50 CMO, Altus RTS and Sonesse 50 ranges. Examples here include the Altus RTS 550R2 (1038170) and the 525A2 Altus RTS 120V Motor (1043423).
What tube does it need?
It needs a 70mm octagonal roller tube. The crown and drive slide onto the motor and lock into the octagonal profile, so the motor turns the tube without slipping. Measure the tube profile before ordering, since round and octagonal tubes take different sets.
What if my tube is a different size?
Somfy offers matching sets for other tubes, such as the Octagonal LT50 60MM Crown/Drive Set (9012233) for 60mm octagonal tube and the LT50 DS78MM Crown/Drive Set (9012239) for DS78mm tube. Pick the set that matches your tube profile.
What else is needed for the install?
Add a motor bracket for the motor head, such as the LT50 Universal Bracket with Spring Clip (9420631) or the LT50 Star Head Motor Bracket (9410651). The 500 Series Databook in the documentation on this page lists tube, crown and bracket pairings.
