The SOUTHWARK METAL 51F10109SD is a 601-series sheet metal register boot designed to transition ductwork to a floor, wall, or ceiling register opening. It measures 10 inches by 10 inches by 9 inches and connects the supply duct to a standard register or grille at the termination point of a forced-air distribution system. This type of fitting is a standard component in residential and light commercial HVAC installations where rectangular duct runs terminate at a register collar.
This register boot is used in forced-air heating and cooling systems where a rectangular supply duct must transition to a floor, sidewall, or ceiling register. It fits into framed cavities between joists or studs and accepts a standard register or grille at the face opening. HVAC installers and sheet metal contractors use this fitting during new construction and renovation duct work.
Designed as an OEM-style replacement or new-installation fitting for standard rectangular forced-air supply duct systems requiring a register boot termination.
Installation is performed by licensed HVAC technicians or qualified sheet metal contractors. Power down the air handler or furnace before connecting or modifying ductwork. Seal all joints with UL-listed duct sealant or metal-backed tape in accordance with local mechanical codes. Secure the boot to the register collar and surrounding framing to prevent movement and air leakage.
