The second side wall having a mirror image first component, a mirror image second component and a mirror image third component arranged in a mirror image horizontal row. The mirror image first components support weight and provide stops for horizontal and angled storage units, the mirror image second components have mirror image angled sliding surfaces for guiding the storage unit to an angled position, and provide stops when the storage unit is horizontal and partly withdrawn from the housing, and mirror image third components have curved surfaces for guiding the unit to the angled position and support weight.
