Common questions
What is this tube for?
It is the roller tube that the shade fabric wraps around, with the Somfy motor mounted inside. Part 1781154 has a 40mm octagonal profile, so it takes crowns and drives made for that shape.
How is the tube sold, and what lengths can I get?
Somfy sells it by the foot in 20 ft increments, with a 20 ft minimum order. Order enough 20 ft lengths to cover your shades, then cut each tube to width during fabrication.
Which Somfy motors fit this tube?
Somfy lists 32 compatible motors, including Sonesse 40 and Sonesse 30 models in RTS, Zigbee, WireFree, RS485, PoE and DCT versions, plus Altus RTS and Roll Up 30 Short models. One example in this store is the Sonesse 404S2 RTS Motor with Fast Connector (1240380).
Which crown and drive do I need?
Choose a set made for the 40mm octagonal profile, such as the LS40 Octagonal Rubberized Crown and Drive Set (9016655). Somfy lists that part for 40mm octagonal tube, so check the profile before you order.
What warranty does it carry?
Somfy covers part 1781154 with a 5-year warranty. Somfy sells it through professional dealers and installers and provides a technical diagram of the tube for fabricators.
