This 5-inch Top Takeoff is a professional-grade metal venting component designed for efficient air distribution in residential and commercial HVAC systems. It functions as a critical transition fitting, allowing you to branch a 5-inch round duct off a flat rectangular main trunk line or plenum. Ideal for heating, cooling, and general exhaust applications—such as range hood venting or localized air supply—this takeoff ensures a secure, airtight connection to optimize airflow. Its durable construction makes it a reliable choice for contractors and DIY enthusiasts looking to repair or expand existing ductwork infrastructure.
