Our 3M™ Fire Barrier Pass-Through Device Round are one-piece hinged metal enclosures designed to prevent the passage of fire, smoke and toxic gas. This easily-installed device is ideal for firestopping penetrations in high traffic areas where telecom, data or electrical cables are frequently added or removed. Intumescent material and foam smoke seals achieve a 3 hour fire protection rating.

Simple and Effective for Protecting Critical Equipment
3M™ Fire Barrier Pass-Through Device Round is an ideal firestop solution for through wall penetrations for cabling. This one-piece, round, hinged metal enclosure features a combination of a fixed firestopping intumescent material and foam smoke seals at each end. The re-enterable device installs quickly and easily for new construction or retrofit applications. It is built for round openings, making it easy to slide into standard holes created by hole saws, masonry dry core or concrete wet core bits. It is suitable for blank penetrations, or it hinges over existing cables. It can be secured using optional mounting brackets or firestop sealants (sold separately). When adding or removing cables in the penetration, technicians simply remove and reinstall the foam plugs instead of the entire device. This Fire Barrier Pass-Through Device is designed to provide years of dependable through-penetration firestopping with no reapplication or maintenance.
