Southwark Metal 28RR_2X12X6 Duct End Boot 2x12 to 6 in

Product Description

The SOUTHWARK METAL 28RR_2X12X6 is a right-offset sheet metal duct end boot designed to transition rectangular ductwork to a round register opening. Fabricated from hot-dipped galvanized steel, it connects a 2 inch by 12 inch rectangular duct end to a 6 inch round collar for register or grille mounting. This type of fitting is a standard component in residential and light commercial forced-air HVAC distribution systems, used wherever the supply trunk or branch duct must terminate at a floor, wall, or ceiling register. HVAC sheet metal mechanics and installers work with this fitting during new construction and retrofit duct installations.

This boot is suited for supply air applications in residential forced-air systems where a rectangular branch duct terminates at a floor or sidewall register location. The right-offset design positions the round collar off-center toward one side, which is useful when the register placement does not align with the center of the duct run. It is installed at the end of a rectangular duct branch and accepts a standard 6 inch round collar connection to the register face.

Key Features

• Right-offset geometry positions the 6 inch round collar toward one side for off-center register alignment
• Hot-dipped galvanized steel construction resists corrosion in typical duct system environments
• Rectangular inlet measures 2 inches by 12 inches to match standard branch duct sizing
• 6 inch diameter round outlet connects to standard round-neck registers and grilles
• Meets ACCA and SMACNA applicable standards for sheet metal duct fittings

Compatibility

Designed as an OEM-style replacement and new-construction fitting for residential and light commercial forced-air duct systems using rectangular branch ducts with a 2 inch by 12 inch end profile terminating to a 6 inch round register collar.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal mechanics. Shut down the air handling unit and isolate the system before cutting into or connecting new ductwork. Secure the boot to the duct with sheet metal screws and seal all joints with mastic sealant or UL 181-rated tape per SMACNA guidelines to prevent air leakage. Follow local mechanical codes and ACCA Manual D requirements for duct system design and fitting installation.
