301 Aluminum Semi-rigid Duct, Flexible, Triple-lock, 3 In. X 8 Ft.

The Lambro 301 is a semi-rigid aluminum duct designed for applications where building codes require all-aluminum construction, such as bathroom fan exhausting and general venting. This flexible duct combines the structural integrity of semi-rigid design with the ease of repositioning needed for tight spaces and complex duct runs. The corrugations throughout the duct prevent collapsing while allowing you to bend it as needed for installation around obstacles and corners.

Aluminum construction makes this duct non-combustible and corrosion resistant. The duct is ideal for applications requiring code-compliant all-aluminum systems in bathrooms and other venting environments.

Features and Benefits

• Non-Combustible: Aluminum construction is totally non-combustible, meeting safety requirements for duct systems in building codes.
• Triple-Lock Design: The corrugated construction provides structural integrity and prevents duct collapse while maintaining flexibility for routing.
• Corrosion Resistant: Aluminum ensures durability in venting applications.
• Code-Compliant: Designed for jurisdictions requiring all-aluminum duct in bathroom fan exhaust and general venting systems.
• Maximum Operating Temperature: Rated for 400°F, suitable for standard exhaust venting applications.
