ABSTRACT:
A conduit assembly which has an inner sleeve and outer sleeve which are proportioned to be concentrically mounted, each of which has a longitudinal slot of approximately the same width is disclosed. The conduits are circular, and a detent is provided on the larger of the conduits to accept and nestingly receive the slot of the smaller conduit when the same is rotated to form a complete circular encasement of the wires or cables which are passed through the conduits. The method of the invention contemplates the steps of forming a hole through a wall, such as a firewall, thereafter, optionally, passing the wires through, or passing the inner and outer sleeve through, and then once the wires are in place, or in anticipation of the wires being inserted, rotating the inner sleeve within the outer sleeve until the sleeve slots are approximately diametrically opposed and the central sleeve slop is secured in the detent. After the wires are in place interiorly of the conduit, a packing is inserted through the conduit assembly. Thereafter a blow out patch is secured to the exterior portion of the firewall on both side, and receives the end of the conduit assembly. The blow out patch, in turn, is secured to the firewall making a complete installation in which there are voids are minimized, which voids could pass smoke, fire, fumes, or other undesirables.
