Abstract: A free-standing shelf support of prefabricated components particularly suited for convenient store or supermarket displays is disclosed. The unit includes two sections each comprising a pair of vertically-disposed uprights mounting therebetween a panel assembly having grooved vertical edges with clips at their upper ends designed to cooperate with slotted tongue protrusions on the uprights to cause the panel assembly to be secured to the uprights simply by being slid downwardly into engagement therewith during assembly. Each upright has a base member which extends laterally from its lower end, and a lower shelf spans across the top of the base members and cooperates with a kickplate extending across the ends of the base members to tie together the lower end of the unit. The uprights are provided with a series of vertically-spaced holes designed to accommodate vertically adjustable shelf supports.
