In one embodiment, a shelving apparatus generally includes a track and a standard. The track includes a support portion having an upper support surface and an extension extending generally outwardly from the support portion. The standard includes a back surface having an opening. When the support portion is within the opening, an upper surface of the opening contacts the upper support surface of the support portion, and the extension is engagingly received within a portion of the opening. This engagement of the extension within the portion of the opening can inhibit disengagement of the standard from the track.
