Fabricated from hot-dipped galvanized steel, this boot transitions from a 12 x 12 inch rectangular opening to an 8-inch round collar, making it a standard component in residential and light commercial supply-air distribution. Licensed HVAC technicians and sheet metal installers use this fitting to connect round branch ductwork to a floor, wall, or ceiling register. Compliance with ACCA and SMACNA standards means it meets recognized industry requirements for duct construction and airflow performance.\u003c\/p\u003e\n\u003cp\u003eThis duct boot is suited for supply-air register connections in residential new construction, renovation, and HVAC replacement projects. The straight configuration simplifies installation in floor or ceiling applications where the duct runs perpendicular to the register face. The rectangular-to-round geometry accommodates round trunk or branch lines feeding a standard 12 x 12 inch register opening. No field fabrication is required for typical installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot-dipped galvanized steel construction resists corrosion in both conditioned and unconditioned spaces\u003c\/li\u003e\n  \u003cli\u003eStraight rectangular-to-round transition — 12 x 12 inch face to 8-inch round collar\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for sheet metal ductwork\u003c\/li\u003e\n  \u003cli\u003eRegister-style boot for direct connection to standard floor, wall, or ceiling registers\u003c\/li\u003e\n  \u003cli\u003eFactory-formed geometry eliminates field-cutting or custom fabrication for standard installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal fitting for forced-air HVAC duct systems requiring a straight rectangular-to-round register boot with a 12 x 12 inch rectangular opening and an 8-inch round collar.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or sheet metal mechanics following SMACNA duct construction standards. Shut down the air handler and de-energize the system before working in the duct system. Secure the boot to the subfloor or framing using appropriate sheet metal screws and seal all joints with UL 181-rated mastic or foil tape per local mechanical code requirements. Do not compress or deform the round collar during installation, as this will restrict airflow and affect system balance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot-Dipped Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace Size (Size A)\u003c\/strong\u003e: 12 inches x 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollar Diameter (Size B)\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Register, Straight, Rectangular to Round\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: 27R_12X12X8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283983139122,"sku":"27R_12X12X8","price":27.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277629.jpg?v=1781065021","url":"https:\/\/voomisupply.com\/products\/southwark-metal-27r_12x12x8-duct-boot-12x12-to-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
