The fitting transitions a 7-inch round duct collar to a 4 x 12 inch rectangular register face, making a 90-degree turn in the process. This configuration is standard when routing supply air from a round trunk or branch duct up through a subfloor or down from a ceiling joist bay into a wall or floor register. HVAC installers and sheet metal mechanics use this boot where a straight drop or a straight-through fitting will not work due to framing constraints or layout requirements. The galvanized finish resists corrosion in typical attic, crawlspace, and basement installations.\u003c\/p\u003e\n\u003cp\u003eThis register boot is used in new construction and retrofit residential duct systems where a round branch duct feeds a floor, ceiling, or wall register. The 4 x 12 inch face opening accommodates a standard 4 x 12 inch floor or sidewall register grille. The 7-inch collar connects directly to 7-inch round flex duct or sheet metal branch piping. The 90-degree elbow geometry suits installations where the branch duct runs perpendicular to the finished register opening, which is common in joist-bay and stud-bay supply runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree elbow geometry for perpendicular duct-to-register transitions\u003c\/li\u003e\n  \u003cli\u003e4 x 12 inch rectangular face opening fits standard residential register grilles\u003c\/li\u003e\n  \u003cli\u003e7-inch round collar for direct connection to 7-inch flex or rigid round duct\u003c\/li\u003e\n  \u003cli\u003eGalvanized steel construction for corrosion resistance in unconditioned spaces\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.50 pounds for easy single-person handling during install\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal fitting compatible with standard residential forced-air supply duct systems using 7-inch round branch duct and 4 x 12 inch register grilles.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified sheet metal mechanics. Shut down the air handler and confirm the system is depressurized before cutting into existing ductwork. Secure the round collar to the branch duct using sheet metal screws and foil-backed mastic or UL 181-listed duct tape per local mechanical code requirements. Fasten the register face flange to the framing or subfloor before installing the finish register grille.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 4 x 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollar Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eElbow Degree\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: 90-Degree Register Boot\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.50 pounds\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: SNAPPY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: p13-427\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SNAPPY","offers":[{"title":"Default Title","offer_id":51233724170546,"sku":"P13-427","price":22.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307630004.jpg?v=1780107491","url":"https:\/\/voomisupply.com\/products\/snappy-p13-427-90-degree-register-boot-4x12-7-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
