Abstract: A cabinet is disclosed having a front frame constructed from four extruded edge members. Each extruded edge member has a running slot internal to it such that it receives a reinforcing member at each corner. The outer enclosure comprises an upper U-shaped panel and a lower U-shaped panel, each having interiorly bent outer edges which are secured by a dove-tail bent clamp positioned therebetween. A rear frame secures the enclosure in wrap-around relationship to both front and rear frames. Interior mounting posts having mounting holes thereon are secured to the front and rear frames by means of a fastener which engages a second running slot adjacent the first. The panels coupled with the mounting members secure the frame members which are reinforced at their corners and the dove-tail bent clamp secures the upper U-shaped closure portion to the lower U-shaped closure portion. The dove-tail bent clamp also forms horizontal handle assemblies on both sides of the cabinet.

Abstract: Building components are disclosed for constructing of frames, enclosures, and the like, comprising hollow edge struts all of uniform cross section, with the ends of each edge strut providing a female joint. Interlocking members are provided having a central member with a plurality of legs extending outwardly from the central member and at fixed angles to each other, the legs each defining a male member adapted to be inserted in said female joint. The legs have locking clip recesses formed therein in at least two adjacent surfaces of the legs, the locking clip recesses spanning substantially the entire width and length of the surfaces of the legs. An abuttment shoulder is formed at the central member and end of the locking clip recess which the edge strut butts up against when installed.
