FIRE-SEAL® Poke-Thru's are designed to prevent fire and smoke from traveling through floor openings used for power and telephone wiring. The devices mount into the 1-3/8-in. 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 block the movement of smoke and fire from floor to floor.
