About 3M Fire Barrier Self-Locking Pillows
The 3M Fire Barrier Self-Locking Pillows are self-contained firestops ideal for medium to large through penetrations. Pillows feature Interlocking strips – installers can easily lock multiple pillows together to achieve precise fill and compression with no additional support required. Intumescent fire-rated pillows are designed to expand during a fire, locking themselves around vital components.
