ABSTRACT:
A cable duct for protecting communication cable is provided, comprising an elongated body portion having a first end and a second end, the body portion further including a longitudinal axis extending between the first end and the second end; and at least two passageways formed completely through the body portion and extending substantially parallel to the longitudinal axis, each of the passageways having a cross sectional area sufficient to loosely contain at least one communication cable. The cable duct is constructed from a combination of materials including plastic and crumb rubber, preferably in a 1:1 composition, and includes a plurality of external ridges formed perpendicular to the longitudinal axis. The body portion further includes end connectors which are removably attachable to the first end and/or second end for connecting the cable duct to a second cable duct. The cable duct can be manufactured with any number of passageways, and with the aforementioned composition of materials, the cable duct can thus be extruded to lengths of at least one kilometer for ease of transportation and installation.
