It is manufactured from 28-gauge galvanized steel and is available with a crimped end for easy connection to standard round duct systems. This fitting is a core component in residential and light commercial HVAC duct installations. HVAC technicians, sheet metal workers, and mechanical contractors use reducers like the 581210A to manage airflow velocity and pressure as duct runs change in diameter. The crimped end allows the fitting to slide directly into the female end of adjoining ductwork, speeding up installation and creating a secure, airtight connection. Galvanized steel construction provides corrosion resistance and long service life in both supply and return air applications. The 28-gauge material offers a solid balance of strength and workability, making it suitable for commercial shop fabrication as well as field installation. At approximately 12 inches in length and 14 inches in width, this reducer fits neatly into standard ceiling, wall, and floor duct chases. The galvanized coating meets typical requirements for HVAC sheet metal components and is manufactured in the USA. Prop 65 compliance information is noted for California installations. Each unit is sold individually and is part of Southwark Metal Product Family 58, a well-established line of round duct fittings. Whether you are building a new duct system or retrofitting an existing one, the 581210A delivers reliable performance as a round-to-round duct reducer transition fitting.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eTransitions round ductwork from 12 inches to 10 inches for airflow management in HVAC systems\u003c\/li\u003e\n\u003cli\u003e28-gauge galvanized steel construction provides corrosion resistance and structural durability\u003c\/li\u003e\n\u003cli\u003eCrimped end design allows quick, secure connection to standard round duct components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Southwark Metal 581210A 3-Piece Reducer is a USA-made, 28-gauge galvanized steel duct fitting that delivers a reliable 12-inch to 10-inch round duct transition with a crimped end for fast, airtight installation.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\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: 581210A\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 12 inches to 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGauge\u003c\/strong\u003e: 28 GA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGalvanized Coating\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProp 65\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 099274520482\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51120861086002,"sku":"581210A","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304885243.webp?v=1777741713","url":"https:\/\/voomisupply.com\/products\/southwark-metal-581210a-3-piece-reducer-12-inches-x-10-inches-crimped-galvanized-steel-round-duct-fitting","provider":"Voomi Supply","version":"1.0","type":"link"}
