This fitting features a 5-inch round opening with a 1.5-inch tab depth, allowing it to seat securely into duct board without the need for additional collars or adapters. It is installed by HVAC technicians during new construction ductwork fabrication or duct system retrofits where fiberglass duct board is the primary trunk material.\u003c\/p\u003e\n\u003cp\u003eThe 84DB1505 is used in residential and light commercial forced-air applications where fiberglass duct board trunk systems are specified. The tab design allows the takeoff to be inserted directly into a cut opening in the duct board panel, creating a secure mechanical connection for branch duct runs. This fitting is a standard component in supply-side duct layouts where 5-inch round branches are required off a duct board main.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-inch round opening for direct connection to 5-inch round branch ductwork\u003c\/li\u003e\n  \u003cli\u003e1.5-inch tab depth for positive engagement with duct board panels\u003c\/li\u003e\n  \u003cli\u003eTab-style mounting eliminates need for separate duct board collars\u003c\/li\u003e\n  \u003cli\u003eDesigned for fiberglass duct board trunk line installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-construction fitting for fiberglass duct board trunk systems requiring 5-inch round branch takeoffs.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians working with fiberglass duct board systems. Power down the air handling unit before cutting into an existing duct board trunk. Use a sharp utility knife or duct board knife to cut the takeoff opening to the correct size before inserting the tab fitting. Seal all joints with UL 181B-rated mastic or approved tape per local mechanical code requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRound Opening Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTab Depth\u003c\/strong\u003e: 1.5 inches\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: 84DB1505\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIR FLOW PRODUCTS","offers":[{"title":"Default Title","offer_id":51346657313074,"sku":"84DB1505","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554544.jpg?v=1782086905","url":"https:\/\/voomisupply.com\/products\/air-flow-products-84db1505-duct-board-tab-takeoff","provider":"Voomi Supply","version":"1.0","type":"link"}
