Constructed from hot dip galvanized steel, this takeoff connects a rectangular or square trunk duct to a 4-inch round branch run. The adjustable design allows the collar angle to be set during installation, making it suitable for a range of duct configurations without requiring custom fabrication. HVAC sheet metal mechanics and duct installers use this fitting in both new construction and retrofit applications where branch supply runs need to be tapped off a main duct.\u003c\/p\u003e\u003cp\u003eThis takeoff is intended for residential and light commercial forced-air HVAC systems where a 4-inch round branch duct is required. It is installed on the main trunk duct at the point of a supply branch takeoff. The adjustable feature accommodates varying installation angles, reducing the need for additional transition fittings. It is well suited for low-pressure supply air distribution systems built to ACCA and SMACNA standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-inch diameter outlet for connection to 4-inch round branch ductwork\u003c\/li\u003e\n\u003cli\u003eHot dip galvanized steel construction for corrosion resistance in air distribution applications\u003c\/li\u003e\n\u003cli\u003eAdjustable collar allows field-set installation angle without custom fabrication\u003c\/li\u003e\n\u003cli\u003eManufactured to ACCA and SMACNA applicable standards\u003c\/li\u003e\n\u003cli\u003eCompatible with standard sheet metal trunk duct construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and new-construction fitting for residential and light commercial forced-air duct systems requiring a 4-inch square to round takeoff connection.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed sheet metal mechanics or HVAC technicians. The air handling system should be shut down and the main disconnect de-energized before cutting into any existing ductwork. Duct openings should be cut to the fitting collar dimensions and secured with sheet metal screws and foil-backed mastic or UL-listed duct tape per SMACNA installation guidelines. Follow local mechanical codes and ACCA Manual D duct design requirements for branch sizing and takeoff placement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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_4IN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284039401778,"sku":"63A_4IN","price":25.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278348.jpg?v=1781066892","url":"https:\/\/voomisupply.com\/products\/southwark-metal-63a_4in-square-to-round-duct-takeoff-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
