4 inch x 10 foot Flexible Aluminum Semi-Rigid HVAC Duct (Crimp-Lock)

The Lambro 4-inch by 10-foot flexible, semi-rigid aluminum duct (crimp-lock) is perfect for general HVAC venting needs, efficiently expelling air from homes. Ideal for HVAC systems, these ducts minimize air leakage and maximize performance, leading to substantial energy savings and enhanced indoor air quality. Suitable for new installations or replacements, the duct's flexibility is ensured by its corrugations, preventing collapse and facilitating easy bending. Crafted from corrosion-resistant, non-combustible, and flame-resistant aluminum, it operates up to 430F. During installation, the duct can be cut to length for optimal airflow. Manufactured from a dead soft aluminum strip, spirally wound and mechanically joined, it forms an airtight, leakproof seam. This self-supporting, corrosion-resistant product offers excellent strength and flexibility, adapting to low to high-pressure HVAC systems. The minimum bend radius is one diameter, with a recommended radius of 1 diameters. Easily cut to size and hand-formed, ensure you check local building codes before installation.
