7 inch x 8 foot Flexible Aluminum Semi-Rigid HVAC Duct (Triple-Lock) – One Crimped End – Item #297F

The Lambro 7-inch by 8-foot flexible, semi-rigid aluminum duct 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. They're great for new installations or replacements. The duct's flexibility, thanks to its corrugations, prevents collapse and allows for easy bending. Aluminum's corrosion resistance, non-combustibility, and flame resistance ensure durability, with a maximum operating temperature of 430F. During installation, you can cut the duct to length for optimal airflow. This lightweight, non-insulated duct features a triple lock seam, formed by spirally winding and mechanically joining a dead soft aluminum strip, creating an airtight and leakproof seal. This self-supporting, corrosion-resistant product offers excellent strength and flexibility, adapting to any low-to-high pressure heating, ventilation, and air conditioning system.
