ABSTRACT:
A display for supporting merchandise includes a horizontal arm assembly comprising a pair of elongated nesting segments that can be selectively and reversibly locked at a number of longitudinally positions relative to each other. One end of the arm assembly is free. The other end connects to an indexing pin assembly that in turn connects to a support structure. A support bracket directly connects to the support structure, for example, a wall, and the arm assembly mounts to the support bracket by a vertical indexing pin that is rotatably supported in support bracket openings and keyed to the support arm. A key on the indexing pin engages any one of a plurality of slots on the support bracket to selectively set the angular position of the arm assembly relative to the support structure. Arm length is adjustable without using tools.
