Each distribution duct has a bottom plate and a plurality of closed cells with less than all of the cells having portions cut away to thus leave free areas under the trenches. An opening is provided in the bottom plate at a de- sired free area, and an open pan extends through the opening and below the bottom plate. The bottoms of the trenches are open where they intersect the ducts to provide access to the pans as well as to provide access between the trenches and the ducts and ad- ditional space below the trench to accommodate splices and bends in the cables. The pans can also be accessed from the floor below via the ceiling suspended below the pans.
