The AIR FLOW PRODUCTS 84RATD06 is an airtight stick-on takeoff fitting designed for round duct pipe with an integrated damper. It provides a sealed branch connection point on rectangular sheet metal ductwork, allowing a round pipe run to be added without cutting and flanging the main trunk. The built-in damper gives the installer direct airflow control at the takeoff point. This fitting is suited for residential and light commercial forced-air HVAC duct systems and is typically installed by sheet metal workers or HVAC technicians during new construction or duct modification work.
This takeoff is used where a 6-inch round branch duct must be tapped off a rectangular main trunk line. The stick-on design uses an adhesive-backed collar that bonds directly to the duct surface, eliminating the need to cut a flanged hole in the trunk. The integrated damper allows the branch airflow to be balanced or shut off independently, making it useful in zoned systems or applications where individual room control is needed.
Designed as an OEM-style replacement or new-installation fitting for standard rectangular sheet metal trunk ductwork in residential and light commercial forced-air HVAC systems accepting a 6-inch round branch connection.
Installation is typically performed by a licensed HVAC technician or qualified sheet metal worker. The air handling system should be shut down and power disconnected before fitting is applied. The duct surface must be clean and dry for the adhesive seal to bond properly. Follow local mechanical codes and SMACNA duct construction standards for branch takeoff placement and airflow balancing requirements.
