This fitting connects branch ducts to a duct board trunk, allowing controlled airflow to individual zones or rooms. The built-in damper provides on-site volume control without the need for a separate balancing damper. At 16 inches, it suits larger branch runs common in residential new construction and retrofit duct systems. HVAC installers and sheet metal workers are the primary trades handling this fitting.\u003c\/p\u003e\n\u003cp\u003eThe 84DBD16 is suited for duct board plenum and trunk systems where branch takeoffs are needed at fixed intervals. It is commonly used in residential forced-air heating and cooling installations where duct board is the primary trunk material. The 16-inch size accommodates higher-volume branch runs serving larger rooms or multiple diffusers. This fitting is a practical choice for jobs requiring field-adjustable airflow without adding secondary hardware to the duct system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIntegrated damper allows field adjustment of branch airflow volume\u003c\/li\u003e\n  \u003cli\u003eTab-style design secures to duct board trunk without additional fasteners\u003c\/li\u003e\n  \u003cli\u003e16-inch size supports higher-volume branch duct runs\u003c\/li\u003e\n  \u003cli\u003eDesigned for low-pressure duct board air distribution systems\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 duct board trunk systems used in residential and light commercial forced-air HVAC applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified sheet metal workers. Power down the air handler and confirm the system is depressurized before cutting into an existing duct board trunk. Secure the tab takeoff per the duct board manufacturer guidelines and seal all joints with approved duct mastic or UL 181-rated tape per local mechanical code requirements. Do not operate the system until all joints are fully sealed and the damper is set to the desired position.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 16 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: 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: 84DBD16\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIR FLOW PRODUCTS","offers":[{"title":"Default Title","offer_id":51345864491314,"sku":"84DBD16","price":40.32,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554487.jpg?v=1782065037","url":"https:\/\/voomisupply.com\/products\/air-flow-products-84dbd16-duct-board-tab-takeoff-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
