4 inch x 8 foot Flexible Semi-Rigid Duct – Item #302L
The Lambro flexible semi-rigid 4 inch x 8 foot duct is ideal for general purpose venting applications including bathroom fan and kitchen range hood exhausting. The corrugations throughout the duct prevents collapsing and allows for easily bending the duct when needed.

If a heavier UL version is needed based on code, Lambro has that covered with our UL certified products.
