Abstract
A trough shade system and method of use provide improved support for a roller tube and shade material. The roller tube and wound shade material are located within a support cradle to minimize unwanted deflection by the roller tube and associated wrinkling and deformation of the shade material. Various mechanisms allow the roller tube a limited range of movement within the support cradle. The system is suitable for shading larger areas than other shading systems which rely on roller tubes with fixed supports at the ends.
