Common questions

What does the LS40 Octagonal Rubberized Crown and Drive Set do?

It connects a Somfy 400 Series motor to 40mm octagonal roller tube. The crown centers the motor in the tube, and the rubberized drive locks into the tube profile to turn the roller. Somfy lists it as the 400 Series Crown and Rubberized Drive for 40mm Octagonal Tube.

Which motors does this set fit?

Somfy lists 22 compatible motors across the Sonesse 40 range, in RTS, WT, Zigbee, RS485 and PoE versions, plus Altus RTS models. Examples we carry include the Sonesse 404S2 RTS Motor with Fast Connector (1240380) and the Sonesse 40 406A2 Zigbee 3.0 Motor (1245921).

What tube does it work with?

It fits 40mm octagonal roller tube, such as the Somfy 40mm Octagonal Tube we sell by the foot (1781154). For 40mm x 1.5mm round tube, choose the LS40 Rubberized Crown and Drive Set (9016654).

What else do I need for a complete shade?

Plan for a 400 Series motor, 40mm octagonal tube cut to width, and the brackets and idler end your shade system uses. This set covers the motor-to-tube connection at the motor end.

Does the set carry a warranty?

Yes. Somfy covers this crown and drive set with a 5-year warranty. It is a genuine Somfy part matched to Sonesse 40 motor heads and the 40mm octagonal tube profile.
