Air Flow Products 84RATD07 Stick-on Takeoff Damper 7 in

Product Description

The AIR FLOW PRODUCTS 84RATD07 is a 7-inch airtight stick-on takeoff fitting designed for round duct pipe with an integrated damper. This fitting connects branch runs directly to rectangular sheet metal trunk lines without the need for cutting or riveting the main duct. The built-in damper allows the installer to balance airflow at the branch point, reducing over-conditioning in one zone while maintaining pressure in the rest of the system. HVAC sheet metal installers and duct fabricators use this type of fitting on new construction and retrofit duct systems where airflow control and airtight performance are both required.

The 84RATD07 is suited for residential and light commercial forced-air distribution systems. It is applied directly to the flat or curved surface of a rectangular trunk duct, creating a branch takeoff point for a 7-inch round duct run. The adhesive mounting system speeds installation and eliminates the need for additional fasteners at the connection point. This fitting is a practical choice for installations where airtightness at the trunk connection is a code or commissioning requirement.

Key Features

• 7-inch round duct connection for standard branch run sizing
• Integrated damper for branch-level airflow balancing
• Stick-on adhesive mount eliminates field cutting of the trunk duct face
• Airtight construction helps meet duct leakage requirements at branch takeoff points
• Compatible with rectangular sheet metal trunk duct systems

Compatibility

Designed as an OEM-style replacement and new-installation fitting for rectangular sheet metal trunk duct systems requiring a 7-inch round branch takeoff with damper control.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal mechanics. Shut down the air handling unit and confirm the system is unpressurized before attaching the fitting to the trunk duct. Clean and dry the trunk duct surface before applying the adhesive mount to ensure a proper airtight seal. Follow local mechanical codes and SMACNA duct construction standards for branch takeoff placement and damper adjustment procedures.
