ABSTRACT:
A roller tube has a tubular wall and a longitudinal axis. A channel runs longitudinally in an exterior surface of the tubular wall and is configured to receive an attachment insert for sheet material such as a solar shade, movie screen, decorative shade or the like. The channel has first and second side walls that extend from an interior portion of the tubular wall toward the exterior surface. The second side wall extends further away from the longitudinal axis of the roller tube than the first side wall. This creates a lip in the exterior surface of the roller tube, enabling the attachment insert to be mounted flush with the exterior surface of the roller tube and avoiding any bumps from being formed in the sheet material as it is wound around the tube. The tube wall varies in thickness and has a relatively thick section to accommodate the channel being formed therein.
