Abstract Of The Disclosure A multi-cable conduit has a housing which is opened at opposite ends, and a plurality of partitions dividing the interior of the housing into a plurality of compartments ex- tending between the open ends. Each of the compartments is sized to receive a multiplicity of cables extending through the compartment and the open ends of the housing, and the compartments are elongated in a direction transverse to the axes of the cables. The partitions are slidably supported within the housing so that each partition can be separately inserted into, and removed from, the housing. A lining of intumescent material is provided on the walls of each compart- ment for expanding into and sealing each of the compartments in response to a fire. Compartments or portions of compart- ments which are not filled with cables are filled with a non- flammable insert. At least one end of each compartment is also sealed to limit the transmission of smoke through the compartments prior to expansion of the intumescent material. Directing means are also provided at the open ends of the com- partments for forcusing the expansion of the intumescent material into the compartments.
