Abstract
Abstract A modular cabinet assembly and components and subassemblies therefor. A sheet metal, L-shaped, back-bottom member provides a pair of longitudinal walls and integral mounting flanges at each side of each wall. The longitudinal edges of the walls are folded to form rigidifying finish edges. Side panels and brackets defining hooks are securable to the mounting flanges to provide a cabinet subassembly which may be hung from slotted supports. The other two longitudinal sides may be closed by a closure panel mounted to angles secured to the side panels, and an openable door. The openable door may be of a variety of types, selectively to provide a plurality of cabinet assemblies, each with an assemblage of identical subassembly components.
