FIRE-SEAL® Poke-Thru seals from O-Z/Gedney prevent fire and smoke from traveling through floor openings used for power and telephone wiring, securing the safety of building occupants and minimizing the costly effects of damage to properties. These simple-to-install devices mount into the 1-3/8-inch holes regularly drilled into metal decks or reinforced concrete slabs to route cable and wire. Upon installation, the high-temperature Pyrolastic™ seal expands against the opening to effectively block the movement of smoke and fire from floor to floor.O-Z/Gedney.
