Southwark Metal 28R_6X14X6 Duct End Boot 6x14x6

Product Description

The SOUTHWARK METAL 28R_6X14X6 is a rectangular-to-round sheet metal duct end boot designed for use in forced-air HVAC duct systems. Fabricated from hot-dipped galvanized steel, this center-end boot transitions a 6-inch by 14-inch rectangular duct opening to a 6-inch round collar, enabling direct connection to a floor or ceiling register. It is installed by HVAC technicians and sheet metal mechanics as the final duct fitting before the register face. The galvanized steel construction resists corrosion in both conditioned and unconditioned spaces, making it a dependable choice for residential and light commercial duct installations.

This boot is suited for residential forced-air supply duct systems where a rectangular trunk or branch run must terminate at a round-neck floor, wall, or ceiling register. The center outlet configuration positions the 6-inch round collar at the center of the 6-inch by 14-inch rectangular face, which supports balanced airflow distribution into the register. It is commonly used in new construction and duct retrofit work governed by ACCA and SMACNA standards.

Installation Notes

Installation is typically performed by a licensed HVAC technician or journeyman sheet metal mechanic. Shut down the air handler and disconnect power before connecting or sealing any duct fittings. Seal all joints with UL 181-rated mastic or approved metal duct tape per SMACNA guidelines to prevent air leakage. Secure the boot to the register and adjoining duct with appropriate sheet metal screws before applying sealant.
