The IMPERIAL MFG GROUP USA INC GV0621-C is a 30-gauge galvanized steel register boot designed to transition a 2.25-inch by 12-inch rectangular duct opening to a 6-inch round collar. This 90-degree boot is a standard component in residential and light commercial forced-air duct systems, connecting branch duct runs to floor, wall, or ceiling register openings. HVAC installers use this boot to terminate a supply duct at the point where a grille or register is mounted. The galvanized steel construction resists corrosion and holds shape under typical HVAC operating pressures. Each unit ships as part of a package quantity of 6.
This register boot is suited for residential new construction and retrofit HVAC installations where a rectangular-to-round transition is required at the register face. It is commonly installed in floor decks, sidewall framing cavities, or ceiling assemblies as the final connection point between the branch duct and the supply register. The 90-degree angle orients the register face perpendicular to the duct run, which is the most common configuration for floor and sidewall supply outlets in residential forced-air systems.
Designed as an OEM-style replacement or new-installation component for residential and light commercial forced-air HVAC duct systems requiring a 2.25-inch by 12-inch rectangular-to-6-inch round register boot transition.
Installation is typically performed by a licensed HVAC technician or sheet metal contractor. Power down the air handler and close the system before cutting into any duct run. Secure the boot to the branch duct using sheet metal screws and seal all joints with UL 181-rated foil tape or mastic sealant per local mechanical code requirements. Do not over-compress the duct collar during fitting, as deformation can restrict airflow.
