Abstract: A plug-assembled multi-shelf sectional display rack constituted of a plurality of horizontal and vertical hollow sections joined together at their ends by corner junctions having vertically and horizontally extending plugs engageable within the hollows of the sections. Each section is provided with a longitudinally extending inwardly facing recess which merges into a hollow longitudinal guide extending axially of the section. Mounted within the recesses and guides of the vertical sections are inwardly extending supports having horizontal surfaces for holding shelves. The supports determine the vertical spacing between the shelves. They include guide sections engageable within the hollow axially extending guides of the sections. Vertical gaps are provided between lateral faces formed on the supports and the walls defining the recesses of the vertical sections to permit insertion of vertical panels.
