Abstract: A reclosable cover for converting a two-piece electrical wire and cable duct system into a one-piece reclosable duct. The cover is fabricated from a dual-durometer plastic co-extrusion having a flexible hinge portion extruded of a resilient lower durometer plastic material. A clip assembly formed along one edge of the cover includes a modified U-shaped channel to receive and clamp the top end of a duct channel sidewall. Flexible fins are provided within this channel to further locate and retain the duct cover. A generally V-shaped hinge support member and dual ridges provide enhanced hinge integrity and an interference engagement therebetween to provide a cover `remain-open` function. The clip assembly and support member share common elements to thereby improve on the space and cost efficiency of the duct cover.

Abstract: A universal plastic siding clip for attaching cables and wires to the outside of a building. The siding clip includes cooperating cable retention mechanisms for both horizontal cable spans and vertical cable drops thereby permitting the use of a single fastener for either or both types of cable runs. The retention mechanisms are spaced to avoid cable interference where both cable types are utilized and, further, to position horizontal cables closer to the wall surface thus making use of the intrinsic protection offered by overlapping siding planks while the vertical runs are spaced sufficiently outwardly from the wall surface to avoid interference with such overlapping planks. Cable recesses are provided to permit multiple and widely varying cable cross-sections and diameters in a single clip model. Further, the clip may be injection molded using simplified tooling without movable core members, side actions and similar apparatus that otherwise increases manufacturing costs.

Abstract: An elongate plastic bag clamp or cable tie defined by a main strap portion, said strap having a plurality of teeth at a tip end thereof and a low profile strap engaging and locking head integrally formed at the other end thereof. The teeth are evenly spaced and oriented perpendicularly to the longitudinal axis of the strap. Further, the teeth are contoured, having a greater height along the center region thereof, to facilitate camming and locking engagement with the head. The head includes a pair of sidewalls extending from the strap and a plurality of semi-flexible retention bars rigidly affixed to, and spanning between, the sidewalls. Each retention bar is deformable in its center region under the camming influence of the strap teeth thereby to permit the passage and locking thereof.

Abstract: An integral plastic clip for retaining flat wire or ribbon cables defining a generally rectangular enclosure. The enclosure includes a planar base member adapted to be mounted to a surface and a strap member extending from the base member and forming the top and two side walls of the rectangular enclosure. The strap is integrally formed onto the base at one end and includes a releasable latch arrangement at its other end to engage the base at that second end thereby completing the rectangular enclosure. Primary and secondary curved and tapered cantilever arms extend inwardly from the top wall. The cantilever arms are provided with contoured tips to facilitate sliding movement of arms during latching engagement of the flat wire bundles.

Abstract: A ducting system for electrical wiring or the like including elongated channels and channel covers and prefabricated channel interface assemblies adapted for rapid non-defacing installation without resort to special tools or precision assembly techniques. The interface assemblies are comprised of alignment members which are adapted to engage two or more channels thereby to automatically position the channels in a predetermined relationship. More specifically, projections are provided on the alignment members which are received within recesses on the ends of the duct channels thereby functioning to properly and automatically orient the several duct channels upon system assembly. The interface assemblies further include removable cover means which bridge and conceal the respective ends of the channels and channel covers thereby eliminating precision cutting of the duct sections.

Abstract: A plastic cover for bridging clips of the type commonly utilized on telephone and communications terminal blocks. The cover is dimensioned to closely conform to the contour of the associated clip and includes partial end walls and nibs which function to enhance retention of the clip. The cover may be field installed on an existing bridging clip without the removal of same, or pre-assembled with a clip prior to installation.
