[57] ABSTRACT

An electrical raceway floor track and a partition embodying such floor track wherein the floor track is an elongate aluminum extrusion with a relatively wide upwardly opening lower channel connected to a relatively narrower upwardly opening upper channel by a solid rigid vertical wall. Wallboards and studs are supported by the upper channel, utilities are disposed between the channels and base trim strips are attached to the lower channel to hide the track and utilities. Electrical boxes and cable shelves are easily mounted between the channels with clips engaging ridges in the channels. Shallow grooves guide during screw insertion and provide lines of weakness for removal of short narrow sections where needed.
