Fabricated from hot dip galvanized steel, this boot provides a durable, corrosion-resistant connection point at the register end of a duct run. The rectangular opening measures 4 inches by 12 inches, mating to a standard floor or ceiling register, while the round collar measures 7 inches in diameter for duct attachment. HVAC sheet metal installers and duct fabricators use this fitting as a terminal component in forced-air supply or return systems built to ACCA and SMACNA standards.\u003c\/p\u003e\n\u003cp\u003eThis pipe boot is suited for new construction and retrofit duct installations in residential forced-air heating and cooling systems as well as light commercial applications. It installs at the terminal end of a round duct run where the duct transitions to a rectangular floor boot or ceiling diffuser opening. The 4 inch by 12 inch register face aligns with standard 4 x 12 register grilles, and the 7 inch collar accepts standard round flexible or rigid duct. Applications include trunk-and-branch supply systems and individual room drops where a round-to-register transition is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dip galvanized steel construction for corrosion resistance in conditioned air environments\u003c\/li\u003e\n  \u003cli\u003eStraight boot profile for direct round-to-register transitions without offset4 inch by 12 inch rectangular opening matches standard floor and ceiling register grille sizes\u003c\/li\u003e\n  \u003cli\u003e7 inch diameter round collar for connection to standard round duct\u003c\/li\u003e\n  \u003cli\u003eFabricated to ACCA and SMACNA applicable standards for duct construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal fitting for use with standard 4 inch by 12 inch floor or ceiling register grilles and 7 inch round duct in residential and light commercial forced-air HVAC duct systems built to ACCA and SMACNA guidelines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified sheet metal duct installers.
