First ramp attachment means protrude outwardly from a first of the opposed faces. There is a hollow channel rail with a first side wall that consists of spaced co-planar wall segments that form a gap making the channel rail generally C-shaped in cross-section, the channel rail has an interior surface that defines an interior channel adapted to accommodate the slider rail with at least one of the opposed edges of the slider rail serving as a bearing surface which slides along the interior surface and the first ramp attachment means protruding through the gap between the wall segments. A second ramp attachment means protrudes outwardly from one of the wall segments.
