The Lambro semi-rigid 4-inch x 8-foot UL 2158A transition duct is ideal for venting an electric or gas clothes dryer to the wall pipe. Most clothes dryer manufacturers recommend UL 2158A-certified semi-rigid ducts. The transition duct is for new and replacement clothes dryer installations. The semi-rigid duct is flexible; the corrugations throughout prevent collapsing and allow for easy duct bending when needed. Aluminum is corrosion-resistant, non-combustible, and flame-resistant, with a maximum operating temperature of 600°F. When installing the duct, you can cut it to length to allow for stretching for maximum airflow. A semi-rigid and lightweight non-insulated flexible duct, triple lock is manufactured using a dead soft aluminum strip, spirally wound and mechanically joined together, forming an air-tight and leakproof triple lock seam.
