Southwark Metal 28R_6X10X8 Sheet Metal D Boot 6x10 to 8

Product Description

The SOUTHWARK METAL 28R_6X10X8 is a sheet metal D boot fitting used to transition from a rectangular duct opening to a round pipe connection at a floor or wall register. Constructed from hot dip galvanized steel, this boot provides a durable, corrosion-resistant connection point in residential and light commercial HVAC duct systems. The rectangular opening measures 6 inches by 10 inches and connects to an 8-inch diameter round collar at the center end. Licensed HVAC technicians install this fitting as part of supply or return duct runout terminations.

This D boot is suited for supply duct systems that terminate at floor, ceiling, or wall registers. The center end configuration positions the round collar at the midpoint of the rectangular face, which is common in residential forced-air systems where runout duct drops or rises to a register box. The 6-inch by 10-inch face mates to a standard register grille opening, while the 8-inch collar connects to round spiral or snap-lock duct. This fitting meets ACCA and SMACNA applicable standards.

Installation Notes

Installation is performed by a licensed HVAC technician as part of forced-air duct system assembly. Power down the air handling system before connecting or sealing any duct components. Sheet metal screws and UL 181-rated mastic or foil tape should be used to seal all joints per applicable mechanical code requirements. Do not modify the collar diameter or rectangular opening by cutting or bending, as this will affect the rated fit and airflow performance.
