The Lambro 3-inch by 50-foot UL 181 Class 1 approved, non-insulated air connector, suitable for HVAC systems at low to medium pressure and exhaust applications. It's made with layers of aluminum/polyester and metalized/polyester, bound with a fire-resistant adhesive that endures up to 250F. A galvanized wire helix reinforces the duct, preventing collapse.
