Southwark Metal 59F6106SD Register Boot with Flange

Product Description

The SOUTHWARK METAL 59F6106SD is a 10 x 6 x 6 inch rectangular register boot with an integral flange, used to transition ductwork to a floor, wall, or ceiling register opening. This fitting connects a rectangular duct run to a standard register face, providing a clean, secure mount point for the grille or register. The flanged collar simplifies installation by giving installers a positive surface to fasten against finished surfaces. It is used in residential and light commercial forced-air HVAC systems and is installed by sheet metal workers and HVAC technicians during new construction and renovation work.

The 59F6106SD is suited for 6 x 6 inch register openings fed by 10 x 6 inch rectangular duct. It fits standard supply-air branch takeoffs in trunk-and-branch and radial duct distribution systems. The 203RF designation indicates a rectangular-to-face configuration, making it appropriate for floor boot applications where supply air is directed upward through a floor register or sidewall applications with the appropriate register face.

Installation Notes

Installation is performed by licensed HVAC technicians or sheet metal workers following local mechanical codes and SMACNA duct construction standards. Shut down the air handling system before cutting into existing ductwork or fastening the boot to the duct run. Secure the boot to the duct with sheet metal screws and seal all joints with UL-listed mastic or foil tape to maintain system pressure. Fasten the flange to the finished floor, wall, or ceiling substrate before mounting the register face.
