Abstract: A modular display unit for articles of merchandise includes a plurality of paired article-supporting fixture members mounted by means of prongs on an upright apertured carrier board secured to a support structure by means of a pair of horizontally spaced vertical posts each of which projects frontwardly of the front surface of the carrier board. In a basic module, each of the paired fixture members has a bottom wall, a front end wall, a rear end wall, and a left-hand or right-hand side wall, so that the two fixture members define an open-topped compartment with a split article-supporting surface constituted by the two bottom walls. To accommodate the posts, a step region of sufficient depth is provided on each fixture member at the juncture between its side wall and its rear end wall.
