摘要：
An improved firestop fitting with a flammable main conduit (11) and extension conduit (12) supporting a non-flam mable sleeve (14) and plug (16). The plug lodges into the sleeve when a harness (17) is melted by heat from a fire below the floor (100 or 101) in which the fitting is mounted which passes into the conduits. The fitting is relatively light and inexpen sive.
