Abstract: An interior partition system wherein with relatively few components, most of which can be roll formed from common sets of roller dies, a wide variety of interior screens or full height partitions can be constructed, thus avoiding the necessity of the manufacture and inventory of a large number of parts. For some parts, where volume may not justify the investment in the required roll sets, other manufacturing techniques may be employed, but such parts are readily compatible with the high volume components and usable interchangeably therewith.

Abstract: A sheet metal face for a structural panel has at least one edge portion bent and folded to define a recessed double-thickness flange. A plurality of longitudinally-spaced slots in the flange are used for attaching mounting members having upwardly facing hooking projections receivable in a hook pocket integral with a wall-hanging structural unit. A non-metallic protector strip may be interposed between the hooking projections and hook pocket. The structural unit has bottom and rear sheet metal panels with an integral assembly flange and assembly hook. A load bar assembly may be interposed between the mounting members and the structural unit.

Abstract: A hanger clip is presented formed of a single elongated strip of metal having spring characteristics and adapted to be manually clipped to an overhead beam, such as "T" bar or the like. The strip has a sharp return bend at approximately midway of its length providing two upwardly extending legs lying close to each other to a common level and then being bent outwardly at an obtuse angle, and again being bent inwardly at the end of the first inclined runs at the same acute angle, thus forming clipping runs of approximately equal length and having their terminal ends spaced from each other. The hooks formed by the acute angle bends are spaced apart, when unstressed, by a distance less than the width of the beam to which the clip is intended to be attached.
