This fitting connects vertical duct runs to floor or wall register openings, transitioning airflow at a 90-degree angle. The boot features a 6-inch inside diameter opening and a 3-1\/4-inch wide by 10-inch long collar, making it compatible with standard rectangular floor register applications. Fabricated from galvanized steel at standard gauge, it provides corrosion resistance suited to supply-air duct systems. HVAC sheet metal installers and duct fabricators are the primary trade installing this fitting.\u003c\/p\u003e\n\u003cp\u003eThis stack boot is commonly used in forced-air heating and cooling systems where supply duct branches drop vertically through floor joists and terminate at floor-mounted registers. The 90-degree turn allows a round duct to transition into a flat-lying boot that sits beneath a standard floor grille. The 3-1\/4-inch width fits the most common floor register slot dimension used in residential construction, and the 10-inch length accommodates a wide range of standard register sizes in new construction and retrofit duct work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-inch inside diameter inlet accepts standard 6-inch round duct branch\u003c\/li\u003e\n  \u003cli\u003e90-degree stack boot configuration transitions vertical duct runs to horizontal floor register openings\u003c\/li\u003e\n  \u003cli\u003e3-1\/4-inch wide by 10-inch long collar fits standard residential floor register slots\u003c\/li\u003e\n  \u003cli\u003eGalvanized steel construction provides corrosion resistance for supply-air applications\u003c\/li\u003e\n  \u003cli\u003eStandard gauge fabrication suitable for residential and light commercial forced-air systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for residential forced-air HVAC duct systems using 6-inch round branch ducts and standard 3-1\/4-inch by 10-inch floor registers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or sheet metal duct installers. Shut down the air handler and confirm the system is de-energized before working on any supply or return duct branch.
