Ready® Firestop Grommet

STI Grommet beauty shot

Specified Technologies offers the perfect solution for firestopping and smoke sealing single or small multi-cable penetrations through drywall: Ready® Firestop Grommets. They're molded from a premium-grade, plenum-rated polymer, with a soft foam inner core that conforms to the cable to form a tight, safe, permanent seal.

Membrane and through-penetrations in rated gypsum board walls are a snap with Ready Firestop Grommets. Just drill a hole, run the cable, snap the grommet around the cable and press it into the wall. For single-sided (membrane) penetrations, use a single grommet; for through-penetrations, drill a hole through both sides of the wall and install grommets back-to-back. Ready Firestop Grommets snap together around cable(s) and lock tightly into the wall. Goodbye messy, costly sleeves, sealant and putty!
