The SNAPPY p17c-406 is a galvanized steel center end register boot designed to connect round ductwork to a floor, wall, or ceiling register opening. The boot transitions a 6-inch round collar to a 4-inch by 10-inch rectangular register face, making it a standard component in residential and light commercial forced-air HVAC distribution systems. The galvanized steel construction resists corrosion and holds up to normal duct system operating conditions. HVAC installers and sheet metal contractors use this fitting during new construction and duct retrofit work to terminate supply or return air runs at the register location.
This center end register boot fits into typical supply air trunk-and-branch layouts where a 6-inch round branch duct feeds a 4-inch by 10-inch floor or ceiling register. The center-end configuration positions the collar at the center of the boot end, which suits straight-run duct drops common in residential forced-air systems. It is compatible with standard 4-inch by 10-inch register grilles and diffusers sold separately.
Designed as an OEM-style galvanized fitting for use with 6-inch round branch ductwork terminating at a 4-inch by 10-inch register opening in residential and light commercial forced-air HVAC systems.
This fitting is typically installed by licensed HVAC technicians or sheet metal contractors as part of duct distribution work. Power down the air handler or furnace and close the system before connecting or modifying any duct runs. Secure the boot to the register box or subfloor framing using sheet metal screws, and seal all joints with UL-listed foil tape or mastic sealant per applicable mechanical codes. Do not compress or restrict the round collar connection, as this reduces airflow and system efficiency.
