Superior 6SPWF Non-Insulated Wall Firestop

The Superior 6SPWF Non-Insulated Wall Firestop is designed to provide safe and compliant passage for 6-inch diameter chimney systems through interior or exterior wall assemblies. This essential component helps maintain required clearances to combustible materials while ensuring proper alignment and secure routing of the chimney pipe through wall penetrations in residential wood-burning installations.

Built for durability and reliable performance, the 6SPWF features a Snap-Lock tab connection design for quick and secure installation. Constructed with 430 stainless steel inner and outer casings and continuous laser-welded seams, it delivers strong resistance to heat and long-term environmental exposure. Certified to UL 103HT and ULC-S629 standards, it is rated for 2100°F intermittent use and 1000°F continuous operation, with a 2-inch clearance to combustibles and backed by a limited lifetime warranty.
