3M Fire Barrier Pass-Through Triple Mounting Brackets PT4TMB, Pair, 4 in, Square – Firestop Solutions

The 3M Fire Barrier Pass-Through Triple Mounting Brackets (PT4TMB) are designed to support and secure 4-inch square fire barrier pass-through devices. These mounting brackets facilitate the installation of firestop devices used to protect electrical, data, communication cables, and plumbing pipes passing through fire-rated walls and floors. As part of 3M’s firestop system solutions, these brackets help maintain fire resistance integrity by supporting intumescent devices that expand under heat to seal penetrations, thus preventing the spread of smoke and fire.
