Patent ID: 7456366

Claim:
A modular raceway system comprising: first and second elongated raceway assemblies having first and second elongated bases, respectively, each of said raceway assemblies further including: a projecting web connected to the base, said base having upper and lower plate portions for abutting a wall, and said plate portions having upper and lower marginal edges respectively, wherein the projecting web is joined to the base intermediate said upper and lower marginal edges to form a T-shaped cross section without sidewalls so as to define upwardly and downwardly open elongated wireways, said base web having a free marginal edge with oppositely projecting elongated lips; and upper and lower elongated raceway cover components having elongated marginal edge portions defining sockets for receiving said projecting lips on said base, and said cover components having opposite edge portions that mate with said upper and lower base marginal edges of said base, said upper and lower cover components cooperating with said base to further define said upper and lower wireways respectively; wherein the first base has a length such that the second base, when located adjacent thereto, can be aligned therewith and spaced there from so as to provide a range of gap spaces between the first and second bases; and at least one coupling member cooperative with the first and second raceways and configured to support said bases in longitudinal spaced alignment with one another across said range of gap spaces.
