Lambro 302L 4-In. x 8-Ft. Flexible Semi-Rigid Aluminum Duct

This premium semi-rigid aluminum flexible yet rigid patented duct is recommended over conventional semi-rigid and foil ducts. This duct requires no elbows as it can form tight 90 degree turns, requiring less space to work. The design creates airtight seams and prevents unraveling while handling. The 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 4 times smaller than the current duct in the market. This reduces space needed for transportation, warehouse, and shelf space in store.
