DuraVent DuraChimney II 10" Chase Top Collar
The DuraVent DuraChimney II 10" Chase Top Collar is a premium factory-built chimney system component designed to provide a clean, finished transition at the top of a chimney chase. Engineered for wood-burning fireplaces, stoves, and solid-fuel heating appliances, this chase top collar ensures a secure and professional installation within the DuraChimney II double-wall chimney system. Its lightweight, unitized design eliminates field assembly of pipe sections, helping contractors achieve faster and more efficient chimney installations.
Built for performance and safety, the DuraChimney II chase top collar works with a double-wall, air-cooled chimney system that keeps the exterior cooler while maintaining a strong internal draft for optimal venting efficiency. The system allows for thermal expansion both radially and lengthwise under high temperatures, ensuring long-term durability. UL 103 listed, it is tested for continuous operation at 1000°F, one hour at 1400°F, and ten minutes at 1700°F, delivering reliable, code-compliant chimney protection and performance.
