It provides a sealed branch connection point where supply air is diverted from a flat duct run to a downstream register or branch line. The airtight construction minimizes air leakage at the takeoff point, helping maintain system pressure and delivery efficiency. This fitting is typically installed by HVAC technicians during new duct installations or duct system retrofits where flat duct configurations are used.\u003c\/p\u003e\u003cp\u003eThe 84ATD04 is suited for residential and light commercial HVAC applications using flat duct layouts. The stick-on design allows the fitting to be adhered directly to the flat duct surface, eliminating the need for cutting a separate collar and simplifying field installation. The built-in damper allows the technician to regulate or shut off airflow to individual zones or runs after installation. This makes the fitting useful in zoned systems or in situations where balancing airflow across multiple branches is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAirtight construction reduces air leakage at branch takeoff points\u003c\/li\u003e\n\u003cli\u003eStick-on installation adheres directly to flat duct surface for faster field work\u003c\/li\u003e\n\u003cli\u003eIntegrated damper allows airflow regulation or shutoff after installation\u003c\/li\u003e\n\u003cli\u003e4-inch outlet size suits common residential branch duct runs\u003c\/li\u003e\n\u003cli\u003eDesigned specifically for flat duct system configurations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for flat duct HVAC systems requiring an airtight stick-on takeoff with damper at a 4-inch branch outlet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed HVAC technician. Power down the air handler and verify the system is depressurized before working on duct connections. Ensure the flat duct surface is clean and free of debris before adhering the fitting to achieve a proper airtight seal. Follow local mechanical codes and ACCA Manual D guidelines for duct branch sizing and airflow balancing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 4 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\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: 84ATD04\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIR FLOW PRODUCTS","offers":[{"title":"Default Title","offer_id":51343066759474,"sku":"84ATD04","price":27.36,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553258.jpg?v=1782015482","url":"https:\/\/voomisupply.com\/products\/air-flow-products-84atd04-stick-on-takeoff-damper-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
