Abstract: Modular display panels adapted to interlock to form a vertical display for supporting and displaying articles are extruded from rigid plastic or aluminum in a one-piece cross section which comprises a plurality of spaced front flanges, a plurality of spaced back flanges and webs connected therebetween. The webs are angles relative to one another forming a channel therebetween in which hook elements are releasably mounted to support articles on the panels. The modular panels are interconnected to one another along their longitudinal edges so that a channel is formed which is identical to the channels on the panels thereby concealing the joints between the panels from view.
