ThermoFlo SR Ducting 12 in x 25 ft
The 2000SR Series Ducting is specifically engineered to handle unconditioned air. It can withstand high heat, high humidity and excessive CFMs without any duct failure or fatigue. 2000SR features a triple laminate with industrial-grade foil casing for durability and an ultra-smooth double sealed core for frictionless, silent airflow. The Carbon Black inner core does not reflect light. Rip-stop prevents tearing, galvanized spring steel maintains duct shape and prevents rust. Made in Canada and engineered for what you need!
