Fabricated from hot dip galvanized steel, this boot provides corrosion resistance suited to HVAC duct systems in both residential and light commercial applications. The rectangular opening measures 4 inches by 10 inches, and the round collar is 5 inches in diameter. It meets ACCA and SMACNA fabrication standards, making it appropriate for installations where documented compliance is required. HVAC sheet metal mechanics and duct installers are the typical tradespeople who specify and install this fitting.\u003c\/p\u003e\u003cp\u003eThis pipe boot is used where a rectangular floor or ceiling register opening must connect to a round branch takeoff in a forced-air supply or return duct system. The center-end configuration positions the round collar at the center of the end panel, which suits typical residential supply boot layouts. It is installed at the termination point of a branch duct run, directly beneath or adjacent to a floor or wall register grille.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHot dip galvanized steel construction for corrosion resistance in HVAC duct environments\u003c\/li\u003e\n\u003cli\u003eRectangular opening: 4 inches by 10 inches to match standard register cutout sizes\u003c\/li\u003e\n\u003cli\u003eRound collar: 5 inches in diameter for connection to round branch duct or flex duct\u003c\/li\u003e\n\u003cli\u003eCenter-end configuration for standard floor and ceiling register boot layouts\u003c\/li\u003e\n\u003cli\u003eCompliant with ACCA and SMACNA standards for sheet metal ductwork fabrication\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-construction fitting compatible with standard 4-inch by 10-inch register openings and 5-inch round branch duct connections in residential and light commercial forced-air HVAC systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed HVAC mechanics or sheet metal duct installers.
