3 in x 6 in x 9 in STI SpecSeal SSB Intumescent Firestop Pillows

SpecSeal Firestop Pillows are through-penetration firestop products resembling small cushions or soft bricks. These intumescent and highly resilient pillows are installed in openings by compressing and stacking into the opening in a brick-like fashion.
