Fire-Stop Pipe Collars

Fill the space between plastic pipes and the fire-rated wall or floor they pass through. Collars expand when heated, so they’ll fill any gaps left if your pipe melts or shrinks. Slip a collar over the end of your pipe and press into the opening in the wall or floor. If your pipe runs through a wall, seal both sides.

Flammability Rating—These collars are tested to ASTM and UL standards for preventing the spread of smoke and flames.

Fire-Stop Sheets

Cut these sheets to any size and shape you need to seal large openings in fire-resistant walls and floors. They’re often used to fill the space around pipes, conduit, and ducts.

Use shears to cut these panels to size, then fasten to your surface with No. 10 self-drilling sheet metal screws (not included). Fill any gaps around the sheet with fire-stop caulk (sold separately) for a tight seal.

Steel—Made of steel, they have a firestop coating that expands when it’s heated. If the equipment passing through these panels melts or shrinks during a fire, this coating will fill the gaps.

Paintable—Once sheets are installed, you can paint over them without losing fire protection.

Flammability Rating—These sheets are tested to ASTM and UL standards for stopping the spread of smoke and flames.
