Measuring 2 inches x 6 inches x 9 inches, it provides up to 3-hour fire protection by intumecing and locking into place when exposed to heat, surrounding penetrants to block the spread of fire, smoke, and toxic gases. The self-locking interlocking strips allow fast, secure installation without tools, making this product appropriate for licensed fire protection contractors and journeyman electricians or plumbers working on firestop-rated assemblies.\u003c\/p\u003e\n\u003cp\u003eThis pillow is suited for residential and commercial construction and renovation projects where cable trays, conduit runs, and blank openings pass through fire-rated floor or wall assemblies. Its re-enterable design makes it a practical choice for active job sites where new services are regularly added or rerouted. Any combination of small, medium, or large 3M Fire Barrier pillows can be used to fill an opening, provided a minimum of 33% compression within the opening is maintained to meet system requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIntumescent fill expands during a fire event to seal the opening and lock the pillow in place\u003c\/li\u003e\n  \u003cli\u003eInterlocking strips enable quick, secure placement in floors or walls without adhesives\u003c\/li\u003e\n  \u003cli\u003eRe-enterable design allows pillows to be removed and replaced when adding or modifying penetrants\u003c\/li\u003e\n  \u003cli\u003eRated for up to 3-hour fire protection in listed through-penetration firestop assemblies\u003c\/li\u003e\n  \u003cli\u003eCompatible with cable trays, conduit, and blank openings in rated assemblies\u003c\/li\u003e\n  \u003cli\u003eSelf-contained product requires no mixing, caulking, or additional compounds at point of install\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in through-penetration firestop assemblies including cable tray, conduit, and blank opening applications in fire-rated floor and wall constructions.

Ensure all penetrants are in their final position before installing pillows, as the assembly must meet the listed system compression requirement of at least 33% within the opening. No power shutoff is required for the pillow installation itself, but all energized cable work in the penetration area should follow standard lockout\/tagout procedures.
