Product Description
Lambro Industries - 302UL-3 The Lambro semi-rigid 4-inch x 3-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. Class 0 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. The duct manufacturing material is 100% aluminum. The certified UL 2158A duct contains a UL marking on each length.
Please be sure to check local building codes before installation. Please check your clothes dryer manufacturer’s manual for proper installation and exhausting of the clothes dryer.
