Lambro 302L 8-Ft. Flexible Semi-Rigid Aluminum Duct (4-In. Diameter)

This Lambro 4 In. x 8 Ft. Flexible Semi-Rigid Aluminum Duct is recommended over conventional semi-rigid and foil ducts. The Class 0 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 semi-rigid duct is reinforced with bead wire helix to always maintain its round shape and 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, this 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.
