It transitions a rectangular trunk duct to a round branch duct, directing conditioned air to individual supply runs in forced-air HVAC systems. The adjustable design allows the installer to position the collar opening to align with branch duct routing without cutting a separate hole pattern. Licensed HVAC technicians and sheet metal contractors install this fitting during new construction and retrofit ductwork projects. Fabrication meets ACCA and SMACNA standards, confirming dimensional and performance compliance with industry duct design requirements.\u003c\/p\u003e\n\u003cp\u003eThis takeoff is used in residential and light commercial forced-air distribution systems where a rectangular main trunk feeds round branch ducts. It mounts directly into the flat face or side of a rectangular sheet metal trunk, providing a leak-resistant connection point for a 6-inch round collar. Typical applications include supply air distribution in gas furnace, heat pump, and air handler systems where trunk-and-branch duct layouts are used. The 6-inch diameter suits standard branch run sizing common in residential supply systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-inch diameter round collar for direct connection to 6-inch round branch duct\u003c\/li\u003e\n  \u003cli\u003eAdjustable design allows collar positioning to match field layout without additional cutting\u003c\/li\u003e\n  \u003cli\u003eHot-dip galvanized steel construction resists corrosion in conditioned-air environments\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for duct system fabrication\u003c\/li\u003e\n  \u003cli\u003eSquare-to-round transition reduces turbulence at the branch takeoff point\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal fitting for use with standard rectangular trunk ducts in residential and light commercial forced-air HVAC duct systems requiring a 6-inch round branch takeoff.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified sheet metal contractors in accordance with SMACNA duct construction standards and local mechanical codes. Shut down and de-energize the air handler or furnace before cutting into the existing trunk duct. Secure the takeoff collar with sheet metal screws and seal all joints with UL 181-rated mastic or approved foil tape to meet duct leakage requirements. Wear appropriate PPE when cutting or handling sheet metal edges.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot-Dip Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollar Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Adjustable Square to Round Takeoff\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ACCA, SMACNA\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: SOUTHWARK METAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 63A_6IN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284103364914,"sku":"63A_6IN","price":17.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278350.jpg?v=1781068610","url":"https:\/\/voomisupply.com\/products\/southwark-metal-63a_6in-6-inch-square-to-round-duct-takeoff","provider":"Voomi Supply","version":"1.0","type":"link"}
