Grabber's 20 oz. Sausage GrabberGard® IFC Intumescent Fire Caulk is suitable for a wide range of firestop applications including through'penetrations, wall and floor joints, and construction gaps. The caulk remains flexible after curing, allowing up to 33% joint movement without cracking. It cleans up easily with water before curing and resists slumping during application. This makes it ideal for projects that require UL or WHi-compliant fire-rated assemblies, ensuring reliable performance in commercial and residential construction.
