Common questions

What is the 70mm Octagonal LT60 Crown?

It is the crown that slides onto the head of a Somfy LT60 motor and centers the motor inside 70mm octagonal tube. That support keeps the roller turning true.

Which motors does it fit?

Somfy lists it for LT60 motors: the 660R2, 680R2 and 6100R2 in CMO, Altus RTS and SJTW versions. In this store that includes the Altus RTS 660R2 (1162271), Altus RTS 680R2 (1164261) and 680R2 CMO (1164013).

Which drive does it pair with?

Somfy pairs it with the LT50/60 Octagonal 70mm Drive (9761002) in the 70mm Octagonal LT60 Set (9012247). The 70mm Octagonal LT50/LT60 Aluminum Drive With Stop (9012227) fits the same tube.

What tube does it need?

It needs 70mm octagonal tube. For DS 78 tube on the same LT60 motors, choose the DS 78 LT60 Crown (9705341), and match the drive wheel to that tube as well.

When should I order the crown on its own?

Order it alone when you already have a matching drive or need to replace the crown on an existing motor. Somfy lists the 70mm Octagonal LT60 Set (9012247) for rolling shutter systems when you need both parts.
