DuraVent DuraChimney II 12" Supplementary Support
The DuraVent DuraChimney II 12" Supplementary Support is a high-performance factory-built chimney system accessory designed to provide additional structural reinforcement for DuraChimney II double-wall chimney installations. Ideal for wood-burning fireplaces, stoves, and solid-fuel venting systems, this supplementary support is part of a lightweight, unitized system that eliminates field assembly of pipe sections, allowing for faster, more efficient chimney installation in residential and commercial applications. It enhances overall system stability where added support is required.
Engineered for safety and durability, the DuraChimney II supplementary support bracket works within a double-wall, air-cooled chimney system that keeps exterior surfaces cooler while maintaining strong internal draft efficiency. The system allows for radial and longitudinal thermal expansion under high heat conditions, ensuring long-term reliability and structural integrity. UL 103 listed, DuraChimney II is tested for continuous operation at 1000°F, one hour at 1400°F, and ten minutes at 1700°F, delivering dependable, code-compliant chimney system support and fire-safe performance.
