Lambro 302l Aluminum Semi-rigid Duct, 4 In. X 8 Ft.

The Lambro 302L semi-rigid aluminum duct is designed for general-purpose venting applications where building codes require non-combustible materials. This 4-inch by 8-foot flexible duct works well for bathroom exhaust fans, kitchen range hoods, and other ventilation needs. Its corrugated construction resists collapsing while allowing you to bend the duct to fit your installation layout.

Aluminum construction makes this duct corrosion resistant and entirely non-combustible, suitable for exhaust applications. The semi-rigid design offers a balance between flexibility for routing and structural integrity for proper airflow. This product is not suitable for clothes dryer exhaust ventilation; for that application, use ducting specifically rated for dryer use.
