Constructed from hot dip galvanized steel, this duct box provides a durable, corrosion-resistant transition point between the supply duct and the floor register opening. The box measures 8 inches by 12 inches at the collar and is 11 inches deep, giving installers the vertical depth needed to route supply air cleanly through flooring assemblies. HVAC technicians and sheet metal contractors install this component during new construction and retrofit projects.\u003c\/p\u003e\n\u003cp\u003eThis duct box is used in floor register installations where a rigid sheet metal boot is required to connect supply ductwork to a floor-mounted grille or register. Its 8 inch by 12 inch opening matches standard register sizes, making it a straightforward fit in typical residential floor layouts. The hot dip galvanized steel construction holds up in the crawl space and sub-floor environments common in floor-supply systems. It meets ACCA and SMACNA standards, which are widely referenced in residential and commercial sheet metal duct installation work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dip galvanized steel construction for corrosion resistance in sub-floor and crawl space environments\u003c\/li\u003e\n  \u003cli\u003e8 inch by 12 inch opening matches standard floor register sizes\u003c\/li\u003e\n  \u003cli\u003e11 inches deep for adequate vertical clearance in flooring assemblies\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for sheet metal duct fabrication\u003c\/li\u003e\n  \u003cli\u003eFloor register type for supply air distribution through flooring systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal duct box for floor register applications in residential and light commercial forced-air supply duct systems requiring an 8 inch by 12 inch boot.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or sheet metal contractors. Shut down the air handling system and lock out power before cutting into existing ductwork or flooring.
