Constructed from hot dip galvanized steel, it provides corrosion resistance suited to long-term HVAC duct installations. The inlet measures 3.25 inches by 10 inches, and the outlet is a 7-inch diameter round collar. HVAC sheet metal contractors and duct installers use this fitting to complete low-profile wall stack runs that terminate at floor registers or wall grilles.\u003c\/p\u003e\n\u003cp\u003eThis end boot fits wall stack duct applications where a rectangular plenum or extended stack transitions to a round duct connection at the terminal end. It is commonly installed in residential new construction and retrofit projects where wall cavity space limits duct depth. The fitting suits forced-air heating and cooling systems that use 3.25-inch by 10-inch wall stack duct as part of the supply distribution layout. Installation is performed by licensed HVAC technicians or sheet metal workers following SMACNA and ACCA duct construction standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dip galvanized steel construction for corrosion resistance in HVAC duct systems\u003c\/li\u003e\n  \u003cli\u003eRectangular inlet of 3.25 inches by 10 inches matches standard wall stack duct sizing\u003c\/li\u003e\n  \u003cli\u003e7-inch diameter round outlet for transition to round collar or register boot connection\u003c\/li\u003e\n  \u003cli\u003eFabricated to SMACNA and ACCA applicable standards for sheet metal duct fittings\u003c\/li\u003e\n  \u003cli\u003eWall stack end boot configuration suited for low-profile cavity installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitting for residential and light commercial forced-air duct systems using 3.25-inch by 10-inch wall stack duct with a 7-inch round outlet connection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed HVAC technician or certified sheet metal worker.
