The multiple channel duct assembly for cables comprises of a plurality of plastic inner ducts
contiguous, co-directionally extending, substantially parallel, in abutting contact with each other, each
of the said inner ducts having cross-sectional areas sufficient to contain at least one cable; and a plastic
outer duct encircling said inner ducts over their entire length to retain them in their contiguous
relationship; wherein said outer duct has a corrugated tubular section including a plurality of
contiguous ridges and troughs extending over the entire length; whereby said assembly is so flexible
that it can be coiled around transportable reels as well as so strong that it can withstand dirt in a trench.
The aspect of inner ducts of plastic with less friction provides sufficiently smooth inside surfaces to the
inner ducts, through which fiber optic cables, electric wires or the likes are inserted.
