3M™ Fire Barrier Tuck-In Wrap Strip WS 200, 2 inch
An intumescent firestopping wrap strip that is precut for 2-inch (50.8 mm) nominal plastic pipe sizes.
3M™ Fire Barrier Tuck-In Wrap Strips are easily pushed into the opening around PVC pipes to provide up to a 3-hour fire rating through concrete floors. Engineered primarily for top-side firestop installations, this product helps eliminate the need for retaining collars, concrete screws, ladders and most other material and equipment necessary for bottom-side installations. Designed to help prevent the passage of fire, smoke and noxious gas through fire-rated wall or floor assemblies.
