Built from hot dip galvanized steel, this boot connects a 4-inch by 10-inch rectangular opening to a 4-inch diameter round collar at the center end position. It is a standard component in residential and light commercial forced-air HVAC duct systems, typically installed by HVAC technicians or sheet metal mechanics at floor, ceiling, or sidewall register locations where a round branch takeoff meets a rectangular boot.\u003c\/p\u003e\n\u003cp\u003eThis pipe boot is used in forced-air distribution systems where a round supply or return duct stub connects to a rectangular register opening. The center-end collar position suits installations where the round pipe enters straight through the end of the boot rather than from an offset angle. Typical applications include residential floor register boots, wall register terminations, and light commercial supply air outlets. It meets ACCA and SMACNA applicable standards, making it appropriate for code-compliant duct installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dip galvanized steel construction resists corrosion in typical duct environments\u003c\/li\u003e\n  \u003cli\u003e4-inch by 10-inch rectangular opening matches standard residential register sizes\u003c\/li\u003e\n  \u003cli\u003e4-inch diameter round collar connects directly to common round duct or pipe stubs\u003c\/li\u003e\n  \u003cli\u003eCenter end configuration allows straight-through pipe entry at the end of the boot\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for sheet metal duct fabrication\u003c\/li\u003e\n  \u003cli\u003eRegister-type boot designed for use with standard floor or wall registers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation sheet metal pipe boot for residential and light commercial forced-air HVAC duct systems requiring a 4-inch by 10-inch rectangular-to-4-inch round center-end transition at a register outlet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified sheet metal mechanics in accordance with SMACNA duct construction standards and local mechanical codes. Power down the air handling system before connecting or disconnecting any duct components. Secure the boot to the duct system using sheet metal screws and seal all joints with UL 181-listed mastic or foil tape to prevent air leakage. Confirm the register frame dimensions match the 4-inch by 10-inch opening before finalizing installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRectangular Opening (Size A)\u003c\/strong\u003e: 4 inches x 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRound Collar Diameter (Size B)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Direction\u003c\/strong\u003e: Center\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Register\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: 28R_4X10X4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284098318642,"sku":"28R_4X10X4","price":16.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278649.jpg?v=1781068533","url":"https:\/\/voomisupply.com\/products\/southwark-metal-28r_4x10x4-sheet-metal-pipe-boot-4x10","provider":"Voomi Supply","version":"1.0","type":"link"}
