Claim Text:
1. An apparatus comprising: a first substantially planar member comprising a first edge and an opposing second edge; an aperture disposed along the first substantially planar member and providing a passageway through the first substantially planar member; a second substantially planar member rotatably coupled to the first substantially planar member and extending from the first edge of the first substantially planar member, wherein the second substantially planar member is rotatable about a first axis; a third substantially planar member rotatably coupled to the first substantially planar member and extending from the second edge of the first substantially planar member, wherein the third substantially planar member is rotatable about a second axis; wherein the second substantially planar member comprises a first edge and an opposing second edge, wherein the first edge of the second substantially planar member is rotatably coupled to the first edge of the first substantially planar member and wherein the second edge of the second substantially planar member further comprises a first at least one serration disposed along at least a portion of the second edge; wherein the third substantially planar member comprises a first edge and an opposing second edge, wherein the first edge of the third substantially planar member is rotatably coupled to the second edge of the first substantially planar member and wherein the second edge of the third substantially planar member further comprises a second at least one serration disposed along at least a portion of the second edge of the third substantially planar member; and wherein the first at least one serration and the second at least one serration are configured to engage an inner surface of a cinder block to increase the friction between the respective second and third substantially planar members and the inner surface of the cinder block and to limit rotational movement of the respective second and third substantially planar members.
