A wall anchor or support comprising a support end portion and a shank portion, a plurality of spaced triangular shaped members affixed to the shank and capable of limited pivotal movement when the shank is inserted in an opening in a wall structure and when force is applied to the anchor in a direction away from the wall structure. The plurality of spaced triangular shaped members have a curved surface and two straight side surfaces with the side surfaces being connected together at adjacent ends forming a joint and the curved surface frictionally gripping an interior surface of the opening when the force applied to the wall anchor in a direction away from the wall is applied, thereby preventing the wall anchor from being dislodged from the wall structure.
