Abstract: A chain link fence system has end, corner, or gate posts, each comprising a tubular metal post with a vertically extending concave groove along at least one side thereof and retaining bands across said groove and a horizontal slot near the top end of the post. A supporting cross bar extends from end, corner, or gate post to end, corner, or gate post and has a horizontally positioned apertured tongue member at each end. The tongue member is positioned in the top slot of the post with the aperture aligned with the vertically extending groove. The end links of a chain link fence are positioned in the vertically extending groove. A retaining rod is inserted downwardly along the tubular post through the aperture in the tongue member, in the groove and beneath the retaining bands and through the end links of chain link fence to secure the cross bar and the chain link fence wire to the post. A cap member covers the top of the post.
