The VALUE COLLECTION 77221260 is a galvanized steel straight register boot designed for residential and light commercial HVAC duct systems. This fitting transitions ductwork to a floor, wall, or ceiling register opening, directing conditioned air from round duct into a rectangular register face. The boot features a 6 inch inside diameter inlet and a 2.25 inch by 12 inch rectangular outlet, making it compatible with standard 2-1/4 inch by 12 inch floor or wall registers. Fabricated from galvanized steel at standard gauge, it delivers adequate corrosion resistance for typical forced-air applications. HVAC technicians and sheet metal installers use this fitting during new construction and duct retrofit work.
This straight register boot is suited for residential forced-air heating and cooling systems where a direct, in-line transition from round duct to a rectangular register is required. The straight configuration simplifies installation in accessible floor cavities, stud bays, and dropped ceiling spaces. It ships as a single unit, making it practical for single-outlet replacements or small-quantity service calls where only one fitting is needed per location.
Designed as an OEM-style replacement or new-installation fitting for residential and light commercial forced-air duct systems using 6 inch round duct and standard 2-1/4 inch by 12 inch rectangular registers.
Installation of register boots is typically performed by licensed HVAC technicians or qualified sheet metal installers. Power down the air handler or furnace at the disconnect before working inside the duct system. Secure the boot to the round duct with sheet metal screws and approved foil tape or mastic sealant per applicable mechanical codes. Ensure the rectangular outlet is flush with the finish surface before securing the register grille.
