This fitting provides a sealed branch connection point that allows airflow to be directed from a main flat duct run into a branch line, while the built-in damper enables flow adjustment or shutoff at the takeoff point. At 18 inches, it suits medium to larger residential and light commercial duct configurations. HVAC sheet metal installers and mechanical contractors work with this type of fitting during duct fabrication and system balancing.\u003c\/p\u003e\n\u003cp\u003eThe 84ATD18 is used in forced-air HVAC systems where flat duct is the primary distribution method. It is suited for residential new construction and retrofit applications where airtight performance is required at each branch takeoff. The stick-on installation method reduces labor compared to traditional mechanically fastened fittings, making it a practical choice for production builds and service replacements alike. The integrated damper allows the installer or balancing technician to set airflow at the branch without adding a separate damper assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAirtight construction reduces conditioned air loss at the branch connection\u003c\/li\u003e\n  \u003cli\u003eIntegrated damper allows airflow adjustment directly at the takeoff point\u003c\/li\u003e\n  \u003cli\u003eStick-on design simplifies installation and reduces field labor\u003c\/li\u003e\n  \u003cli\u003e18-inch size suits medium to large branch duct runs in flat duct systems\u003c\/li\u003e\n  \u003cli\u003eDesigned for flat duct configurations common in residential and light commercial HVAC\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for flat duct HVAC distribution systems requiring an airtight branch takeoff with damper control.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or sheet metal contractors. The system blower and any associated electrical controls should be powered down before working on duct connections. Duct surfaces should be clean and free of debris before applying the stick-on fitting to ensure a proper airtight seal. Local mechanical codes and ASHRAE duct sealing standards should be observed when completing the branch connection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Type\u003c\/strong\u003e: Flat Duct\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper\u003c\/strong\u003e: Integrated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Type\u003c\/strong\u003e: Airtight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Stick-On\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 84ATD18\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIR FLOW PRODUCTS","offers":[{"title":"Default Title","offer_id":51346587812146,"sku":"84ATD18","price":72.05,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554418.jpg?v=1782084591","url":"https:\/\/voomisupply.com\/products\/air-flow-products-84atd18-stick-on-takeoff-damper-18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
