A fiber optics cable raceway is formed of main channel members and telescope members. The main channel members have a generally U-shaped cross-section with a base, sides, and, at the top, inwardly extending lips. The telescope members have the same cross-section, but are slightly larger so they can fit about the main channel members for a longitudinally sliding fit. By alternately, interfitting main members and telescope members and adjusting the length by telescopic sliding, a raceway of the desired length can quickly be assembled. Small locking clips can then be fitted about the respective overlapping lips of two members to prevent further sliding. The raceway can be installed below the floor by the use of brackets hanging on pre-existing floor-supporting pedestals. It can be installed above a dropped ceiling by the use of hangers clamped to the grid struts of the ceiling. The locking clips serve to electrically interconnect the channel members and the telescope members.

A cable raceway adapted to be supported from pre-existing internal building structures, said raceway including a plurality of channel members, each said channel member being formed of stiff sheet material and including a bottom portion, sides extending upwardly from said bottom portion, and lips extending inwardly from said sides along the upper edges of said sides, thereby having a generally upright U-shaped cross-section, telescope members having a cross-section complementary to said channel members and being so shaped and dimensioned as to telescopically interfit with said channel members, the extent of said interfit being continuously variable, each said telescope member being formed of stiff sheet material and including a bottom portion, sides extending upwardly from said bottom portion of said telescope members, and lips extending inwardly from said sides of said telescope members along the upper edges of said sides of said telescope members sides, thereby having a generally U-shaped cross-section, said telescope members each telescopically joining two said channel members at the respective proximate ends thereof, a locking clip fitting about parts of said lips of said channel members and said telescope members to hold them against relative longitudinal motion, and brackets having securing means proximate to the upper ends of said brackets for supporting said channel members and said telescope members from said building structures at spaced intervals, whereby said raceway has telescopic length flexibility for easy installation.
