Fabricated from hot-dipped galvanized steel, it delivers corrosion resistance suited for both residential and light commercial forced-air distribution systems. The rectangular inlet measures 4 inches by 12 inches, and the oval outlet is 7 inches in diameter. HVAC installers use this fitting when routing supply air from a trunk or branch duct into a floor, wall, or ceiling register box. Manufactured to ACCA and SMACNA standards, it meets the dimensional and performance requirements common to residential duct system design.\u003c\/p\u003e\u003cp\u003eThis boot is intended for supply air applications in forced-air heating and cooling systems where a rectangular-to-oval transition is required. It fits standard register configurations and is a common component in new construction and retrofit ductwork where a 90-degree offset between the duct run and the register face is needed. It is suited for use in residential and light commercial installations following SMACNA duct construction guidelines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHot-dipped galvanized steel construction for durability and corrosion resistance\u003c\/li\u003e\n\u003cli\u003e90-degree rectangular-to-oval geometry for direct register-to-duct transitions\u003c\/li\u003e\n\u003cli\u003eRectangular inlet: 4 inches by 12 inches\u003c\/li\u003e\n\u003cli\u003eOval outlet: 7 inches in diameter\u003c\/li\u003e\n\u003cli\u003eManufactured to ACCA and SMACNA applicable standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for residential and light commercial forced-air duct systems requiring a rectangular-to-oval, 90-degree boot transition at the register opening.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or sheet metal installer. Power down the air handling unit and shut off the system before connecting or modifying ductwork. Secure the boot to the duct with sheet metal screws and seal all joints with UL 181-rated mastic or foil tape in accordance with SMACNA installation standards. Do not compress or deform the oval outlet, as this will reduce airflow and affect register performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot-Dipped Galvanized Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Size (Rectangular)\u003c\/strong\u003e: 4 inches x 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Size (Oval)\u003c\/strong\u003e: 7 inches diameter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Register, 90 Degree, Rectangular to Oval\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ACCA, SMACNA\u003c\/li\u003e\n\u003c\/ul\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: 124R_4X12X7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284089438514,"sku":"124R_4X12X7","price":43.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277355.jpg?v=1781068279","url":"https:\/\/voomisupply.com\/products\/southwark-metal-124r_4x12x7-sheet-metal-duct-boot-4x12-to-7-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
