Abstract
A control and suspension system for a retractable covering mounted on a rotating element includes an apparatus for mechanically limiting over-extensions of the covering and an apparatus for mechanically limiting over-retractions of the covering. The control and suspension system also includes an apparatus to compensate for any undesirable skewing of the covering that might occur. Finally, the control and suspension system also includes a bottom rail that attaches to the bottom of the covering by trapping a portion of the covering between a compression plate and a bottom plate.
