In Alpha’s current range, we have no offering between 50Nm and 100Nm, which is why there is such a large jump in motor size. The RED 100Nm listings in the 2.75 inch tube section below indicates that this motor is not compatible with a 2.75 inch tube, due to its physical size.

Note: Either the Universal or Folding Arm motors can be used, however you should always choose the Cassette Awning motor if using a sun/wind or motion sensor due to additional protective features. Although the 100Nm motor is a Universal, it also has the extra protective properties.
