ABSTRACT:
A duct system is disclosed for telephone cables and other cables and conductors. The duct system includes a conduit having multiple bores each adapted to contain a cable, and a hollow, tubular duct branching from the conduit and adapted to contain a single cable or group of cables. The duct system also includes a connection adapted at one end to be attached to the conduit and to communicate with one of the bores of the conduit and adapted at the other end to be attached to the end of the tubular duct. The connection provides an easily and economically installed means for connecting single bore tubular ducts to multiple bore conduits which maintains the integrity of the duct system, may be formed of a long-life plastic material, and which provides a smooth interior surface for the pulling of cables therethrough.
