The 2000 SR Series Ducting is specifically engineered to handle unconditioned air, high heat, high humidity and excessive CFM’s without any duct failure or fatigue. 2000 SR features a triple laminate with industrial grade foil casing for durability, and an ultra-smooth double sealed core for frictionless and silent air flow. The “Carbon Black” inner core does not reflect light. “Rip-stop” prevents tearing, galvanized spring steel maintains duct shape and prevents rust. The SR series is c-ETL-us certification tested and verified to conform to UL181 standards.
