The body is fabricated from 30-gauge ASTM A653 CS Type B G40 hot-dip galvanized steel, with a heavier 28-gauge galvanized steel collar for added rigidity at the connection point. The flat-back design allows the boot to sit flush against framing or subfloor surfaces. This fitting is installed by sheet metal and HVAC technicians during new construction and renovation ductwork projects.\u003c\/p\u003e\n\u003cp\u003eThis duct boot is suited for residential and light commercial forced-air HVAC systems where a rectangular trunk or branch feeds a round-collar register drop. The rectangular inlet measures 6 inches by 12 inches and the round collar measures 8 inches in diameter, making it a common size for floor and sidewall supply register applications. It conforms to ACCA, SMACNA, and NATE applicable standards, ensuring it meets recognized industry fabrication and installation guidelines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStraight rectangular-to-round geometry transitions a 6x12 inch rectangular opening to an 8-inch round collar\u003c\/li\u003e\n  \u003cli\u003eBody fabricated from 30-gauge ASTM A653 CS Type B G40 hot-dip galvanized steel for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e28-gauge galvanized steel collar provides additional rigidity at the duct connection point\u003c\/li\u003e\n  \u003cli\u003eFlat-back construction allows flush mounting against framing, subfloor, or wall cavities\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA, SMACNA, and NATE applicable standards for duct fabrication\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard OEM-style sheet metal fitting for residential and light commercial forced-air supply duct systems requiring a rectangular-to-round transition at a floor, wall, or ceiling register location.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC or sheet metal technicians in accordance with SMACNA duct construction standards and local mechanical codes. Shut down the air handler and de-energize the system before connecting or modifying ductwork. Secure the collar connection to the round branch duct using approved sheet metal screws and seal all joints with UL 181-rated mastic or foil tape to prevent air leakage. Confirm the flat-back orientation is correct for the register location before securing the boot to framing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Straight, Rectangular to Round, Register\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize A (Rectangular Inlet)\u003c\/strong\u003e: 6 inches x 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize B (Round Collar)\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material Thickness\u003c\/strong\u003e: 30 Gauge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollar Material Thickness\u003c\/strong\u003e: 28 Gauge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: ASTM A653 CS Type B G40 Hot-Dip Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack Style\u003c\/strong\u003e: Flat Back\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ACCA, SMACNA, NATE\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: PH76128\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51346040357170,"sku":"PH76128","price":19.7,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555194.jpg?v=1782069467","url":"https:\/\/voomisupply.com\/products\/southwark-metal-ph76128-duct-boot-6x12-to-8-inch-30-gauge","provider":"Voomi Supply","version":"1.0","type":"link"}
