The SOUTHWARK METAL 24R_6X14X6 is a 90-degree rectangular-to-round sheet metal duct boot designed for register connections in residential and light commercial forced-air systems. Fabricated from hot-dipped galvanized steel, this boot transitions from a 6-inch by 14-inch rectangular opening to a 6-inch round collar, making it a standard fitting for supply air delivery at floor, wall, or ceiling register locations. HVAC installers use this type of fitting to terminate trunk or branch duct runs at the register grille. The galvanized construction resists corrosion in typical duct environments and meets ACCA and SMACNA fabrication standards.
This duct boot is suited for new construction and replacement applications in residential forced-air heating and cooling systems. It fits where a branch duct connects to a floor or wall register, converting the round branch to a flat rectangular register face. The 90-degree offset geometry positions the register face perpendicular to the branch run, which is the standard orientation for most floor and sidewall register installations. HVAC sheet metal contractors and mechanical installers handle this fitting during rough-in or duct replacement work.
Designed as a standard register boot fitting for residential and light commercial forced-air duct systems requiring a rectangular-to-round 90-degree transition at a 6-inch by 14-inch register opening with a 6-inch round branch connection.
Installation is performed by licensed HVAC technicians or qualified sheet metal contractors. Power down the air handling system and close the fuel or electrical supply before working in the duct system. Secure the round collar to the branch duct with sheet metal screws and seal all joints with UL-listed foil tape or mastic per SMACNA duct construction standards. Do not use this fitting as a structural support for other duct sections.
