Abstract: A fastener clip for use in constructing a security wall system, and a security wall system so constructed are disclosed. The fastener clip has an elongate smooth surfaced planar body, a counter-sunk fastener recess formed s centrally within the body, a fastener opening defined within the recess and extending therethrough, and at least two spaced prongs formed as a part of the body which extend away from the body in a common direction. The fastener recess is sized and shaped to fit within an opening of a rigid mesh wall panel placed in registry with at least one structural frame member of a building. A threaded fastener is passed through the fastener opening and driven into the frame member to seat a bottom portion of the recess and a driving head of the fastener against the frame member.

Abstract: An extruded strip joining system including a strip and a clip which cooperate to join free ends of extruded strips in precise abutment to maintain alignment of the strips. The strip joining system includes the strip which has an elongated junction portion and at least one elongated flange extending parallel to and away from the junction portion. The junction portion includes an internal surface and an external surface. Protruding structures are provided on the internal surface of the junction portion. A pair of axially elongated tabs are formed on the protruding structures depending from internal surface of the junction portion. The tabs are axially elongated along the strip and extend inwardly defining a channel therebetween. The clip is configured to engage the tabs thereby retaining the clip in the channel. Two strips are positioned with free ends abutting each other and a clip is positioned over the channel and pressed into engagement with the tabs.

Abstract: A banding bead which is attachable to a base structure for providing a guide and form for retaining plaster or other plastic materials thereagainst at two different heights. The banding bead includes a base portion and a generally planar elongated support segment extending generally perpendicularly away said base portion. The banding bead is extruded from a selected material or formed from a strip of sheet material. The support segment has a first planar side, a second planar side, and a top screed portion distal the base portion. A screed lip is disposed on the second planar side between the top screed portion and the base portion. The base portion includes primary and secondary feet extending from the support segment for attachment to the underlying base structure and to provide stability.
