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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7-inch round duct connection for standard branch run sizing\u003c\/li\u003e\n\u003cli\u003eIntegrated damper for branch-level airflow balancing\u003c\/li\u003e\n\u003cli\u003eStick-on adhesive mount eliminates field cutting of the trunk duct face\u003c\/li\u003e\n\u003cli\u003eAirtight construction helps meet duct leakage requirements at branch takeoff points\u003c\/li\u003e\n\u003cli\u003eCompatible with rectangular sheet metal trunk duct systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned 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.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation 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.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRound Pipe Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamper\u003c\/strong\u003e: Integrated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Stick-On Adhesive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Connection Type\u003c\/strong\u003e: Round Takeoff to Rectangular Trunk\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAirtight Construction\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: AIR FLOW PRODUCTS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 84RATD07\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIR FLOW PRODUCTS","offers":[{"title":"Default Title","offer_id":51347440075058,"sku":"84RATD07","price":22.46,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553372.jpg?v=1782105039","url":"https:\/\/voomisupply.com\/products\/air-flow-products-84ratd07-stick-on-takeoff-damper-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
