Common questions
What does the LS40 Rubberized Crown and Drive Set do?
It connects a Somfy 400 Series motor to 40mm round roller tube. The crown centers the motor in the tube, and the rubberized drive grips the tube to turn the roller. Somfy lists it as the 400 Series Crown and Rubberized Drive for Somfy 40mm x 1.5mm Round Tube.
What tube size does it fit?
Somfy sizes this set for 40mm round tube with a 1.5mm wall. We sell Somfy 40mm Round Tube by the foot (1781118). Check your tube's outside diameter and wall thickness against that size before you order.
Which motors does this set fit?
Somfy lists 22 compatible motors, including Sonesse 40 RTS, WT, Zigbee, RS485, WireFree and PoE models, Altus RTS models and the 412R2 RH. Examples we carry include the Sonesse 40 404S2 WT 120V 4-Wire Motor with fast connect (1240377).
What if my 40mm tube is octagonal?
Choose the LS40 Octagonal Rubberized Crown and Drive Set (9016655). It fits Somfy 40mm octagonal tube and works with the same Sonesse 40 motor family as this round-tube set.
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 x 1.5mm round tube profile.
