Product Description

The 3M 7010353046 is a manufactured collar designed to complete the installation of a 3M Fire Barrier Duct Wrap 615+ enclosure at butted joints. Applied over the joint where two sections of duct wrap meet, this collar maintains the integrity of the firestopping system by sealing the connection point. It is sold in roll form and is used in commercial and residential construction wherever duct penetrations require a rated firestop assembly. HVAC mechanics and firestopping contractors install this collar as part of a code-compliant duct wrap enclosure system. Each roll weighs 6.24 pounds and measures 1.5 inches wide by 6 inches in face width by 25 feet in length.

This collar is used wherever 3M Fire Barrier Duct Wrap 615+ is installed to protect HVAC ductwork passing through fire-rated walls, floors, or ceilings. It is appropriate for both new construction and retrofit firestopping applications. The collar is applied at butted joint seams to ensure continuity of the rated assembly. Installers working on commercial tenant improvements, multifamily residential projects, or institutional buildings will encounter this product as a required component of the 615+ duct wrap system.
