Fire safety isn’t just about alarms and extinguishers—it's also about stopping fire before it spreads. The Metacaulk Firestop Collar is a key component used by builders and contractors to protect plastic pipe penetrations through fire-rated walls and floors. When exposed to extreme heat, the collar’s intumescent material expands rapidly, sealing off the opening and helping to contain the fire. It’s UL-tested, easy to install, and compatible with various pipe sizes. Whether you’re working on a commercial project or upgrading fire protection in a residential space, this collar meets key building code requirements and provides critical peace of mind. It’s a small investment with potentially life-saving benefits—making it a trusted choice for professionals in firestop systems.
