Abstract: A storage shelving module preferably expandable in three dimensions so as to vary the size and capacity of the module without the need to supplement or replace component parts. The module includes first and second frame sub-assemblies, each of which includes four telescoping elements. Each telescoping element defines horizontally and vertically extending leg members. Each of the horizontally extending legs defined by a telescoping element in each of the two sub-assemblies is disposed in a telescopic relationship with another horizontally extending leg in the same sub-assembly and the vertically extending legs in the first sub-assembly are disposed in telescopic relationship with the vertically extending legs in the second sub-assembly.
