Firestop Typical Applications:

A UL-Classified firestop used to seal cable trays, cable, piping and other items that penetrate through fire-rated walls and floors. The product firestops large blanks and provides a smoke seal (when used in conjunction with MC 1000 Sealant or MC Moldable Putty M) for any shape opening in concrete block or slabs. Use MC Composite Sheet to shield cable trays, conduit, HVAC ductwork, panels, valves and vital heat-sensitive process equipment. The product is effective in protecting cable drop-outs, junction boxes and cabinets, as well as in providing an intermittent firestop in horizontal and vertical cable tray runs.
