Additional Information
Pillows remove easily when adding new services. Self-contained, intumescent product for use in a wide variety of through-penetration firestops including cable trays, conduit and blank openings.

During a fire, 3M™ Fire Barrier Self-Locking Pillows intumesce (expand) and lock themselves into place, surrounding the penetrant(s) to help prevent the spread of smoke, fire and toxic gases.

Any combination of small, medium, or large pillows can be used to firestop an opening provided the minimum compression requirements are met (minimum of 33% within the opening).
