Alpha crowns and drives connect compatible tubular motors with the roller tube used in motorised blind and awning systems. Selecting the correct components is important because different roller tubes can have different internal diameters and profiles. Frontline Supply stocks Alpha crowns, drives, adaptors and related components for compatible Alpha tubular motor installations. Options are available across different Alpha motor sizes and roller tube configurations. When replacing an existing crown and drive, don’t rely on the outside diameter of the tube alone. Check the Alpha product code where available and compare the internal tube dimensions and profile with the compatibility information provided on each product page. Not sure which one you need? Use our Match Your Existing Blind Tube to the Correct Crown & Drive measurement guide to help identify the appropriate component before ordering.
