The Lambro semi-rigid 6-inch by 8-foot T-LOCK UL 181 Class 0 HVAC air duct is perfect for supply, return, or exhaust systems. Its corrugated design provides flexibility, preventing collapse and enabling easy bending as needed. Crafted from 100% aluminum, it resists corrosion, is non-combustible, and flame-retardant, withstanding temperatures up to 600F. The T-LOCK design features a lightweight, flexible air duct made from a soft aluminum strip that's spirally wound and mechanically fastened, creating a leakproof and airtight triple lock seam. During installation, there are no length restrictions for the air duct. Each section of this certified UL 181 Class 0 air duct bears the UL certification mark. Before installation, ensure you check local building codes.
