The tab-style design allows the fitting to lock securely into duct board without requiring separate fasteners at the takeoff point. The built-in damper gives the installer direct airflow control at the branch point, making balancing residential or light commercial duct systems faster during commissioning. HVAC technicians and sheet metal installers working with duct board systems are the primary installers of this fitting.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for residential and light commercial forced-air HVAC applications where fibrous glass duct board is used as the primary distribution medium. The 4-inch diameter makes it a common choice for individual room supply branches off a main duct board trunk. The integrated damper eliminates the need to install a separate inline damper downstream, saving time on system balancing at startup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch diameter tab takeoff sized for standard branch supply runs\u003c\/li\u003e\n  \u003cli\u003eIntegrated damper allows airflow balancing directly at the branch takeoff point\u003c\/li\u003e\n  \u003cli\u003eTab design locks into duct board for a secure, tool-friendly installation\u003c\/li\u003e\n  \u003cli\u003eEliminates need for a separate inline balancing damper on the branch\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install fitting for fibrous glass duct board HVAC distribution systems requiring a 4-inch tab takeoff with damper.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or qualified sheet metal installer. The air handling unit or furnace should be powered down and the system de-energized before cutting into the duct board and installing any takeoff fitting. Use tools and adhesives appropriate for fibrous glass duct board as specified by the duct board manufacturer and local mechanical codes. Ensure the damper blade moves freely and is set to the desired position before sealing the duct system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Tab Takeoff with Damper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Fibrous Glass Duct Board Systems\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: 84DBD204\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIR FLOW PRODUCTS","offers":[{"title":"Default Title","offer_id":51343869247794,"sku":"84DBD204","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554540.jpg?v=1782025197","url":"https:\/\/voomisupply.com\/products\/air-flow-products-84dbd204-duct-board-tab-takeoff-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
