Q.What can I do if my aluminium roller blind tube isn't 38mm or 45mm?
A. All of the DC tubular motors come with free of one drive wheel adapter and one crown which works with 38mm or 45mm aluminium blind tubes. However, if your aluminium tube roller blind tube is a different size we have several types of drive wheel adaptors and crowns for 44-46mm tubes. Just send an inquiry form along with photos which show the interior shape of the tube and let me know all necessary measurements (inside diameter and outside diameter), we will find out if we have the appropriate drive wheel adaptor and crown to match your tube and send to you if you order the iSW range of tubular motors through us.
