IEP STI Closet Flange Firestop Gasket
The die cut rubber gasket is perforated to delineate removable inserts sized to accommodate various outer diameters of toilet flanges. Traditional firestopping methods require the firestop material to be applied around the pipe prior to setting the toilet flange, which can be problematic if the firestop material is not recessed a sufficient distance from the top to accommodate the throat of the flange. The alternative is to apply the firestopping from the underside of the floor, necessitating the use of ladders or lifts. SpecSeal Closet Flange Firestop Gaskets solve the problem by providing a labor-friendly method of properly firestopping the opening.
