Lambro 306 8-Ft. Flexible Semi-Rigid Aluminum Duct (6-In. Diameter)

This Lambro semi-rigid, aluminum, flexible yet rigid patented duct is recommended over conventional semi-rigid and foil ducts. The 6-in. x 8-ft. duct requires no elbows as it can form tight 90° turns requiring less space to work. The design creates airtight seams and prevents unraveling while handling. The Class 0 duct is reinforced with bead wire helix to always maintain its round shape. This duct is suitable for all general-purpose venting applications including exhaust venting, bathroom fan venting, range hoods and more. It is installer friendly and can be uncompressed easily for installation. Unlike conventional semi-rigid ducts that take up large amounts of space, the duct has a compact compression that is 4x smaller than many current ducts on the market. This reduces space needed for transportation, warehouse, and shelf space in store.
