Kind Code:
A
Abstract:
The multiple channel duct assembly for cables includes a plurality of plastic inner ducts (10) contiguous, co-directionally extending, substantially parallel, and in abutting contact with each other. Each of the inner ducts (10) has a cross sectional area sufficient to contain at least one cable. A plastic outer duct (20) encircles the inner ducts over their entire length to retain them in their contiguous relationship. The outer duct (20) has a corrugated tubular section including a plurality of contiguous ridges (21) and troughs (22) extending over their entire length. The assembly is sufficiently flexible that it can be coiled around transportable reels as well as sufficiently strong that it can withstand dirt in a trench.
