A gondola standard cap comprises a relatively long and flat front wall with smooth and backwardly curved side edges. The gondola standard cap is provided on its rear with vertically aligned and spaced resilient ears which allow the cap to be installed into the holes of vertical posts in metallic shelving systems. The cap is provided with a plurality of vertically aligned knock-out tabs which are selectively removed as needed for alignment with the holes of the vertical post of the metallic shelving system to accommodate the ears of the brackets of the shelving system. In this way, the gondola standard cap will close off the holes of the vertical posts and prevent any injury by contact with the holes of the posts.
