Large Diameter Firestop Sleeves

With multiple size options, these large diameter sleeves help make firestopping bigger pipes quicker and more affordable. They come with a few features you can’t find anywhere else on the market: a 12-inch sleeve option, a 1-inch stackable extension — which can serve as a water dam when two are installed together after concrete is poured — and an OSHA-compliant safety cap. Available in standard and hollow versions for use with metal, insulated and plastic pipe penetrations.
