The LUKJAN METAL PRODUCTS RB106106 is a center end register boot designed to transition a 6-inch round duct to a 10-inch by 6-inch rectangular register opening at a 90-degree angle. Fabricated from galvanized steel, this boot delivers corrosion resistance, structural rigidity, and long-term durability in forced-air distribution systems. The center end configuration aligns the duct opening to the center of the boot, supporting precise register placement. It is installed by HVAC technicians in residential and light commercial ductwork systems as part of supply air distribution runs.
This register boot is suited for residential and light commercial HVAC installations where a round trunk or branch duct must terminate at a floor, wall, or ceiling register. The 6-inch round inlet accommodates standard round duct, and the rectangular outlet accepts a 10-inch by 6-inch register or grille. The center end orientation is commonly used in floor and ceiling installations where centered airflow delivery is required. Typical applications include new construction, duct renovation, and system retrofits.
Designed as an OEM-style replacement and new-installation component for residential and light commercial HVAC ductwork requiring a 6-inch round to 10-inch by 6-inch rectangular end boot transition.
Installation is performed by licensed HVAC technicians or qualified sheet metal contractors. Shut off the air handling unit and confirm the system is de-energized before beginning duct work. Secure the boot to the round duct using sheet metal screws and seal all joints with UL-listed foil tape or mastic sealant in accordance with local mechanical codes. Verify the rectangular outlet aligns flush with the register or grille opening before fastening.
