Shop Alpha crowns and drives for compatible 30mm tubular motors and roller tube systems. Select the correct fitting by matching your motor, roller tube dimensions and internal tube profile.
Alpha 30mm Crown & Drives Alpha 30mm crowns and drives provide the connection between compatible Alpha 30mm tubular motors and the roller tube used in a motorised blind system. Different roller tubes can use different internal diameters and profiles, which means the correct crown and drive must be selected for the particular tube rather than simply choosing by motor size. The 30mm Alpha range includes crown and drive sets, individual drives and adaptors designed for different compatible installations. Some Alpha fittings are designed for specific tube sizes or profiles, while others have specialised applications. Where Alpha specifies a particular tube compatibility, this information is provided on the individual product page. When replacing an existing crown or drive, compare the Alpha product code where available along with the dimensions and profile of your existing roller tube before ordering.
