This fitting connects branch ducts to a main trunk line in forced-air HVAC distribution systems. It serves as a starting collar, allowing HVAC installers to transition from a rectangular trunk duct into a branch run. The 10 x 10 inch profile fits standard rectangular duct configurations. Hot dip galvanized construction provides corrosion resistance suited to both conditioned and mechanical spaces. Licensed HVAC technicians and sheet metal workers install this fitting as part of new construction or replacement ductwork assemblies.\u003c\/p\u003e\n\u003cp\u003eThis collar is intended for residential and light commercial forced-air duct systems where a straight starting takeoff is required on a rectangular trunk. It is manufactured to ACCA and SMACNA standards, making it appropriate for systems designed and installed under those guidelines. The rectangular body pattern suits trunk-and-branch duct layouts common in gas furnace, air handler, and packaged unit installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dip galvanized steel construction for corrosion resistance in HVAC duct environments\u003c\/li\u003e\n  \u003cli\u003eStraight body pattern simplifies installation at trunk duct starting points\u003c\/li\u003e\n  \u003cli\u003eRectangular profile sized at 10 x 10 inches for standard trunk duct applications\u003c\/li\u003e\n  \u003cli\u003eManufactured to ACCA and SMACNA applicable standards\u003c\/li\u003e\n  \u003cli\u003eStarting collar design allows direct branch takeoff from main rectangular trunk\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for rectangular trunk duct systems requiring a straight 10 x 10 inch starting collar takeoff, in compliance with ACCA and SMACNA duct construction standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or journeyman sheet metal workers. The system should be fully powered down and the air handler or furnace shut off before modifying any duct section. Fasten the collar securely to the trunk duct using sheet metal screws and seal all joints with UL-listed duct mastic or metal-backed tape per SMACNA guidelines. Follow local mechanical codes and ACCA Manual D duct design requirements for proper sizing and airflow balance.\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\u003eSize\u003c\/strong\u003e: 10 inches Length x 10 inches Width\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Pattern\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Starting, Rectangular\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: 20_10X10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283986415922,"sku":"20_10X10","price":22.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277143.jpg?v=1781065132","url":"https:\/\/voomisupply.com\/products\/southwark-metal-20_10x10-trunk-duct-collar-10x10-in","provider":"Voomi Supply","version":"1.0","type":"link"}
