It provides a sealed branch connection point that allows airflow to be directed from a main flat duct run into a branch line, with the built-in damper enabling flow adjustment at the takeoff point. The airtight construction minimizes duct leakage, supporting system efficiency in forced-air HVAC applications. The 12-inch size suits a range of residential and light commercial duct configurations. Licensed HVAC technicians and sheet metal installers are the primary users of this fitting.\u003c\/p\u003e\n\u003cp\u003eThis takeoff is intended for flat duct installations in forced-air heating and cooling systems. The stick-on design allows the fitting to be applied directly to the flat duct surface, simplifying branch connections during new installations or retrofits. It is appropriate for residential and light commercial applications where airtight duct construction is required to meet energy codes or system performance targets. The built-in damper allows the installer to balance airflow at each branch without adding a separate damper component.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAirtight construction reduces duct leakage at branch takeoff points\u003c\/li\u003e\n  \u003cli\u003eIntegral damper allows airflow balancing at the point of connection\u003c\/li\u003e\n  \u003cli\u003eStick-on installation method simplifies attachment to flat duct surfaces\u003c\/li\u003e\n  \u003cli\u003e12-inch size suits a range of residential and light commercial duct branch applications\u003c\/li\u003e\n  \u003cli\u003eDesigned for flat duct systems, compatible with common forced-air HVAC configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for flat duct systems in residential and light commercial forced-air HVAC applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified sheet metal installer. Power down the air handler or furnace and close the system before making duct modifications. Ensure the flat duct surface is clean and free of debris before applying the stick-on fitting to achieve a proper airtight seal. Follow local mechanical codes and SMACNA duct construction standards for branch takeoff installation and airflow balancing procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 12 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: Integral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Type\u003c\/strong\u003e: Airtight\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: 84ATD12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIR FLOW PRODUCTS","offers":[{"title":"Default Title","offer_id":51346413060402,"sku":"84ATD12","price":43.59,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554433.jpg?v=1782079464","url":"https:\/\/voomisupply.com\/products\/air-flow-products-84atd12-stick-on-takeoff-damper-12-in","provider":"Voomi Supply","version":"1.0","type":"link"}
