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.
