It measures 14 inches wide by 20 inches long by 12 inches tall and carries an R8 insulation rating. This return air box is built from 26-gauge galvanized steel, giving it strong resistance to rust and corrosion in attic, crawl space, and basement installations. The galvanized finish also helps the unit hold up in humid environments where bare metal would degrade quickly. HVAC technicians and sheet metal contractors rely on return air boxes like the RABR8142012 to connect return air grilles to duct systems efficiently. The flanged design simplifies attachment to ductwork and speeds up installation, reducing labor time on the job. The R8 insulation value meets or exceeds energy code requirements in many jurisdictions, helping limit thermal loss and condensation on the exterior of the box. This is especially important in unconditioned spaces where temperature differentials between inside and outside the duct can cause moisture problems. The Southwark Metal RABR8142012 is manufactured in the USA, which supports consistent quality control and reliable dimensional accuracy. It ships as a single unit and is part of Southwark's RAB product family, a trusted line of return air components used widely across the HVAC trade. Whether you are replacing a damaged return air box or building out a new system, this unit delivers a solid, code-friendly solution. The combination of heavy-gauge steel construction, factory insulation, and flanged ends makes the RABR8142012 a practical choice for professional installers working on forced-air heating and cooling systems.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eR8 insulation rating reduces thermal loss and meets common energy code requirements\u003c\/li\u003e\n\u003cli\u003e26-gauge galvanized steel construction resists rust and corrosion in unconditioned spaces\u003c\/li\u003e\n\u003cli\u003eFlanged design speeds up duct connections and simplifies installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Southwark Metal RABR8142012 is a USA-made, R8-insulated return air box in 26-gauge galvanized steel, sized at 14 inches x 20 inches x 12 inches with flanged ends for fast, reliable duct system 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: RABR8142012\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 14 inches x 20 inches x 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 20 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGauge\u003c\/strong\u003e: 26 GA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComposition\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eR-Value\u003c\/strong\u003e: R8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlanged\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGalvanized\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\u003eProduct Family\u003c\/strong\u003e: RAB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51121013391666,"sku":"RABR8142012","price":90.45,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304885208.webp?v=1777745888","url":"https:\/\/voomisupply.com\/products\/southwark-metal-rabr8142012-return-air-box-r8-insulation-14-inches-x-20-inches-x-12-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
