3M 051115-16530 Fire Barrier Duct Pillow, Fb249, 2 In H X 4 In W X 9 In L, Small

The 3m 051115-16530 Fire Barrier Duct Pillow Fb249 is a specialized firestop solution designed to provide a temporary or permanent seal for large openings in fire-rated construction. These small-sized pillows are engineered to expand when exposed to heat, creating a tight pressure seal that prevents the spread of fire, smoke, and toxic gases through wall and floor penetrations.

• Compressible design allows for easy installation in tight spaces or around complex penetrations without the need for specialized tools.
• Intumescent properties ensure the pillow expands during a fire to maintain a robust barrier as surrounding materials may consume or shift.
• Re-enterable and reusable construction makes them ideal for projects requiring frequent cable changes or temporary firestopping during construction phases.

This product is best suited for electrical contractors, facility maintenance teams, and construction professionals working in commercial or industrial buildings where fire-rated cable trays and large openings require reliable protection.

• Size: 2 In H x 4 In W x 9 In L
• Model: FB249 (Small)
• Part Number: 051115-16530
