Patent ID: 7262371

Claim:
A modular raceway system comprising elongated raceway subassemblies, each of said raceway subassemblies including an elongated base having upper and lower plate portions for abutting a wall, said plate portions having upper and lower marginal edges respectively, coupling means for supporting said bases in longitudinal spaced alignment with one another to provide a range of gaps, between first and second raceway bases, said first raceway base having a length such that an adjacent second elongated base associated with an adjacent raceway subassembly can be aligned therewith, and be spaced therefrom, so as to provide a range of gap spaces between said first and second raceway bases, said first and second elongated bases each having a projecting web joined to said base plate portion intermediate said 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 of L-shape cross-section and 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 respectively cooperating with said base to further define said upper and lower wireways respectively.
