Abstract
Abstract An integral display panel formed of wood composite material provided with a plurality of spaced parallel horizontally extending grooves having a modified T-shaped cross-section, and a substantially sheet-form insert mounted within each of said grooves, each of the inserts having a modified T-shaped cross-section defining a chamber adapted to receive and retain metal or plastic hangers having enlarged base portions which engage the internal wall surfaces of the inserts to hold the hangers on the panels with the hanger arms extending outwardly and normally transverse to the face or surface of a panel, each insert having a web and a pair of flanges arranged in converging relationship, with the outer surface of the converging wall of each flange being provided with a longitudinal bead engaging the surfaces of the groove, each flange terminating in a hook-form lip, the lips directed outwardly with respect to each other and engaging the edges of the grooves of the panel to provide more positive retention and an improved esthetic appearance.
