ABSTRACT:
An anchor for attaching cables or other devices to a wall structure comprises a hollow metal cylinder having a pair of wing members pivoted within the cylinder and extending through opposing openings in the sides of the cylinder. The wings are spring biased to their collapsed positions in the cylinder and are extended by the pressure of a bolt threaded in one end of the cylinder. The wings may be forced by the bolt to wedge the cylinder in a concrete or other solid wall, alternatively may be extended in back of a panel wall for retaining the anchor in place.
