Tab takeoffs provide a secure, leak-resistant connection point where branch ducts split from a main trunk. This fitting is part of the 84DB series and is sized at 16 inches to match standard duct board trunk dimensions. HVAC sheet metal workers and duct fabricators install this fitting during new construction or retrofit duct system builds. It is a critical component for maintaining proper airflow routing and system efficiency in residential and light commercial applications.\u003c\/p\u003e\u003cp\u003eThe 84DB16 is used in fibrous glass duct board systems where branch takeoffs are required along the main supply trunk. It is suited for residential forced-air heating and cooling systems as well as light commercial air distribution layouts. The tab design allows the fitting to lock securely into the duct board surface without additional fasteners, streamlining installation in tight mechanical spaces or attic runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e16-inch sizing for compatibility with standard duct board trunk applications\u003c\/li\u003e\n\u003cli\u003eTab design locks into duct board without additional fasteners\u003c\/li\u003e\n\u003cli\u003ePart of the 84DB series for consistent fitment across branch takeoff configurations\u003c\/li\u003e\n\u003cli\u003eSupports low-pressure air distribution system layouts\u003c\/li\u003e\n\u003cli\u003eSuitable for residential and light commercial HVAC ductwork\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style fitting for fibrous glass duct board systems requiring a 16-inch branch takeoff connection point.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by licensed HVAC technicians or qualified duct fabricators. Shut down the air handling unit and confirm the system is de-energized before working on any duct section. Tabs should be fully seated and sealed at the duct board surface using approved duct sealant or foil tape per SMACNA guidelines to maintain system integrity. Do not over-compress the duct board when inserting the fitting, as this can distort the connection and reduce airflow performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 84DB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Duct Board Tab Takeoff\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: 84DB16\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIR FLOW PRODUCTS","offers":[{"title":"Default Title","offer_id":51346641289522,"sku":"84DB16","price":24.49,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553291.jpg?v=1782086354","url":"https:\/\/voomisupply.com\/products\/air-flow-products-84db16-duct-board-tab-takeoff-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
