Abstract
Abstract A furniture assembly combination which includes component panels to be assembled together in positions normal to each other and a hardware assembly composed of a receptacle bar and a support bar, each with the same or complementary cross-section to interfit with angled bearing surfaces in contact to draw the parts together. One element of the hardware is recessed in a panel and the other element projects from another panel so that the parts interfit to rigidly join the panels.
