A load covering device includes two opposing hinge boxes, each hinge box having a pair of structural plates. Each of the pair of structural plates defines a matched progression of holes, the matched progression of holes having two terminal holes and at least one central hole. The device includes a number of rib members, each having two ends, with one end interposed between and pivotally coupled to corresponding holes of the structural plates of each hinge box. A rib member having ends positioned at one of the terminal holes in each of the hinge boxes is a terminal rib member, and the terminal rib member includes a fixed bend, the fixed bend being in a plane parallel to the structural plates. |
