Grommet strip

A grommet strip of the type including a spring tempered metal substrate strip having an elongated base portion and a plurality of discrete spaced apart finger portions extending in a common direction from each longitudinal edge of said base portion and substantially normal thereto, inner surfaces of said base and finger portions forming an elongated channel with an open end opposite to said base portion and adapted to receive an exposed edge of a wall with the inner surface of said base portion juxtaposed to the exposed edge and said inner surfaces of said finger portions engaging marginal sections of the wall directly adjacent to the edge, and wherein said finger portions extending from each of said edges are substantially spaced apart so as to establish therebetween strip voids each bounded by an exposed edge of said base portion and facing side edges of longitudinally adjacent said finger portions;

• and wherein the improvement comprises a resilient non-metallic coating providing an elongated resilient surface covering over a surface of the base portion facing opposite to said channel and providing over each of said exposed edges of said base portion a resilient edge length surface that forms with said elongated resilient surface covering an angle substantially greater than 90.degree. and thereby providing between said surface covering and said edge length surfaces a gradual transition that reduces abrasion to insulated electrical wires retained by said grommet strip.
