Abstract: A one-piece clip simultaneously supports and grips a shelf when the clip is secured between a support pole and the shelf edge by a screw which penetrates the pole, the clip and the shelf consecutively. The longitudinal clip is die-cut and has a central base portion which abuts an indentation in the pole. An aperture centered in the clip base portion is aligned with screw holes horizontally penetrating the pole prior to insertion of the screw. Parallel arms extend up from the base portion of the clip, elbows attached thereto connect angled arms which extend outwardly and terminate in clip ends which flushly abut the exterior surface of the support pole.
