The EZ-Path retrofit device is designed to restore the ratings for overfilled cable sleeve penetrations. The device features a built-in fire and smoke sealing system that can attach either to the sleeve or the barrier surface. The EZ-Path retrofit device consists of a heavy gauge galvanized steel housing containing intumescent materials that expand rapidly when exposed to fire or high temperatures to close off the void area. Its unique two-piece design quickly installs around cable bundles and extended sleeves and can even accommodate standard conduit bushings. The square device shape allows cable exit or entry from multiple directions.
