The LUKJAN rb106107 is a center end register boot designed for residential and light commercial ducted HVAC systems. This sheet metal boot transitions from round duct to a rectangular floor, wall, or ceiling register opening, directing conditioned air into the living space. It measures 6 inches by 10 inches at the register face with a 7-inch round collar, and weighs 0.5 pounds. HVAC technicians and sheet metal installers use this fitting during new construction and retrofit duct installations where a center end configuration is required for proper register alignment.
This boot is suited for forced-air heating and cooling applications where round duct transitions to a rectangular register. The center end design positions the round collar at the center of the boot's end, which is common in floor and sidewall register installations. It fits into standard residential trunk-and-branch and plenum-style duct systems where register placement demands a centered collar entry.
Designed as an OEM-style sheet metal fitting for residential and light commercial forced-air ducted HVAC systems requiring a center end register boot with a 7-inch round collar and a 6-inch by 10-inch rectangular register opening.
Installation is performed by licensed HVAC technicians or qualified sheet metal workers. Power down the air handling unit and close the system before cutting into existing ductwork. Secure the boot to round duct using sheet metal screws and seal all joints with UL-listed foil tape or mastic sealant per applicable mechanical codes. Do not compress or kink flex duct connections at the collar, as this reduces airflow and system efficiency.
