It connects a 15 inches by 14 inches rectangular duct opening to a 14 inches round collar, making it a critical fitting for routing supply or return air between square or rectangular plenums and round duct runs. HVAC technicians, sheet metal contractors, and mechanical installers rely on transitions like this one to adapt ductwork layouts where the duct shape changes direction or connects to differing equipment ports. This fitting is fabricated from 28 gauge hot dipped galvanized steel meeting ASTM A653 CS Type B standards, providing corrosion resistance and long service life in both residential and light commercial duct systems. The galvanized coating protects the steel from moisture and rust, which is especially important in attic, crawlspace, and basement installations where humidity levels can vary. The overall dimensions are 15 inches in length, 14 inches in width, and 12 inches in height, with a 14 inches round collar diameter. Collar height is approximately 2 inches on fittings up to 16 inches in diameter, providing a secure connection point for standard round duct or flex duct. This transition ships as a single unit and is manufactured in the USA. Southwark Metal is a well-known supplier of sheet metal duct fittings trusted by trade professionals for consistent quality and fit. Whether you are building out a new duct system or replacing a damaged transition, the 73C151414 is a reliable choice for rectangular to round duct connections in forced air heating and cooling applications.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eConnects 15 inches x 14 inches rectangular duct to 14 inches round collar for flexible duct system layouts\u003c\/li\u003e\n\u003cli\u003eFabricated from 28 gauge hot dipped galvanized steel per ASTM A653 CS Type B for corrosion resistance and durability\u003c\/li\u003e\n\u003cli\u003eMade in the USA with approximately 2 inches collar height for standard round duct connections\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Southwark Metal 73C151414 rectangular to round transition provides a reliable, galvanized steel connection between rectangular and round ductwork, built to ASTM standards for long-term performance in residential and commercial HVAC installations.\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: 73C151414\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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\u003eLength\u003c\/strong\u003e: 15 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollar Diameter\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Size\u003c\/strong\u003e: 15 inches x 14 inches to 14 inches Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollar Height\u003c\/strong\u003e: Approximately 2 inches (up to 16 inches diameter)\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\u003eWeight\u003c\/strong\u003e: 3.14 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUOM\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 099274691977\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProp 65\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51120906109234,"sku":"73C151414","price":42.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304885222.webp?v=1777742961","url":"https:\/\/voomisupply.com\/products\/southwark-metal-73c151414-rectangular-to-round-transition-15-inches-x-14-inches-x-14-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
