ABSTRACT:
A sleeve system and method for using same provides an encasement for wires and cables passing through a wall or floor. The sleeve system is particularly useful in allowing the walls within a building to meet fire code requirements. The sleeve system can be used regardless of whether the wiring or cabling has already been installed through the wall or floor. The invention includes a pair of mating sleeve units individually inserted around the cables through the wall or floor and appropriate securing devices for tightly retaining the sleeve units in place. In one embodiment, the securing devices include at least one slotted flange and a slotted coupler on each side of the wall. The sleeve construction also allows easy installation of additional cables through the sleeve.
