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.
