    Nelson™ Firestop MCT Cable Transit System

    Nelson

    The Nelson™ Firestop MCT Cable Transit System is a proven mechanical cable and pipe sealing system, for use in commercial building wall and floor penetrations, as well as in marine bulkhead and deck applications. This cable transit system provides protection from fire, smoke, water and blast pressures, at the point where cables and pipes penetrate the building walls and floors. The MCT is a fire rated, environmental sealing system , comprised of welded frames and Tecron rubber based modules, that provides the most secure and tight system available in the industry from cable pullout, and against shock and vibration.
