Abstract: An outdoor cover assembly for removably covering material positioned on a base surface adjacent a vertical outdoor wall surface. The cover assembly includes a cover structure formed of a single unitary molded fiberglass member and including a top wall, a front wall, side walls, an open back, and an open bottom. Hinge means are provided to mount the rear edge of the top wall of the cover structure at a location on the vertical wall surface at a distance above the base surface approximating the height of the cover structure and a pair of gas struts are provided to assist the cover structure in its movement between a lowered storage position and a raised access position. The struts are attached at their lower ends to bracket members secured to the wall surface proximate the base storage surface and secured at their upper ends to the inboard faces of the respective side walls of the cover structure.
