Abstract: An improved horizontal support member for a demountable wall system which decreases the number of pieces which must be cut and folded, and subsequently assembled, to form a frame to which the gypsum board panels of the wall are assembled while increasing the strength and stability of the wall. The support member is formed from an elongate sheet of metal by making a series of longitudinal cuts in the metal and then folding the cut metal edges along lines which are substantially parallel to the longitudinal cuts to form first and second bars. The space between longitudinal cuts acts as a spacer to maintain the first and second bars in spaced, substantially parallel relationship.

Abstract: A demountable wall system having studs and component parts capable of being used as a fully reinforced or edge grip system simply by turning the studs over. The studs are provided with cut-outs for receiving either the angled member of a suspension clip or receiving the ends of horizontal support members between a retaining member extending outwardly from the stud representing the cut-out portion of the stud and the surface of the stud. In both configurations, a gypsum board panel is supported by the suspension clip, which includes a gang nail plate which is driven into the panel, having the angled member thereof resting either directly in the cut-out of the stud or on a horizontal bar member which rests on the stud.
