Southwark Metal 28R_6X12X6 Sheet Metal Duct End Boot

Product Description

The SOUTHWARK METAL 28R_6X12X6 is a center-end sheet metal duct boot that transitions from a rectangular duct opening to a round collar, designed for residential and light commercial HVAC duct systems. Constructed from hot-dipped galvanized steel, this register boot connects a 6 inch by 12 inch rectangular opening to a 6 inch round collar at the center end position. It is installed by HVAC technicians as part of forced-air duct distribution systems to terminate duct runs at floor, wall, or ceiling register locations. Compliance with ACCA and SMACNA standards ensures it meets recognized industry fabrication and installation requirements.

This duct end boot is suited for use in forced-air heating and cooling applications where a rectangular-to-round transition is required at the register opening. The center outlet configuration positions the round collar at the center of the rectangular face, which is common in floor boot installations serving standard floor registers. It fits into new-construction and retrofit duct work where a 6 inch round feed line terminates at a 6 by 12 inch register opening.

Key Features

• Hot-dipped galvanized steel construction for corrosion resistance in conditioned and unconditioned spaces
• Rectangular opening measures 6 inches by 12 inches to match standard register sizes
• 6 inch diameter round collar connects directly to 6 inch round duct or flex duct
• Center end outlet position for standard floor register boot installations
• Meets ACCA and SMACNA applicable standards for duct fabrication and performance
• Rectangular-to-round transition eliminates the need for a separate adapter fitting

Compatibility

Designed as an OEM-style replacement and new-construction fitting for residential and light commercial forced-air duct systems requiring a 6 inch by 12 inch rectangular-to-round center end boot configuration.

Installation Notes

Installation is performed by licensed HVAC technicians or sheet metal workers following SMACNA duct construction standards and local mechanical codes. Power down the air handling system before connecting or modifying duct sections. Secure the round collar to the connecting duct with approved sheet metal screws and seal all joints with UL 181-rated mastic or foil tape to prevent air leakage. Ensure the rectangular register opening is flush with the finished floor, wall, or ceiling surface before fastening the register grille.
