Southwark Metal 24_3-1/4X10X6 Wall Stack Elbow Boot

Product Description

The SOUTHWARK METAL 24_3-1/4X10X6 is a hot-dip galvanized steel sheet metal duct boot designed for wall stack applications in residential and light commercial HVAC duct systems. This fitting transitions from a rectangular duct opening measuring 3-1/4 inches by 10 inches to a 6-inch diameter round collar at a 90-degree elbow, directing conditioned air from the vertical wall stack into the supply register. It is fabricated from hot-dip galvanized steel for corrosion resistance in both exposed and enclosed wall cavities. HVAC sheet metal installers and mechanical contractors are the primary trades working with this component.

This boot is used in forced-air heating and cooling systems where the supply trunk or branch duct runs vertically inside a wall cavity and terminates at a floor, wall, or baseboard register. The 90-degree elbow geometry suits installations where the duct must change direction from vertical to horizontal at the point of air delivery. It fits standard framed wall cavities that accommodate a 3-1/4 inch by 10 inch rectangular opening, and connects to 6-inch round flexible or rigid branch ductwork on the collar end.

Key Features

• Hot-dip galvanized steel construction resists corrosion in wall cavity environments
• 90-degree elbow geometry transitions from vertical wall stack to horizontal register outlet
• Rectangular inlet measures 3-1/4 inches by 10 inches to fit standard wall stack framing
• 6-inch diameter round collar connects to standard flexible or rigid branch duct
• Meets ACCA and SMACNA applicable standards for sheet metal duct fabrication

Compatibility

Designed as an OEM-style replacement or new-installation fitting for residential and light commercial forced-air duct systems using standard wall stack configurations with a 3-1/4 inch by 10 inch rectangular duct section and 6-inch round branch connections.

Installation Notes

Installation is performed by licensed HVAC technicians or sheet metal mechanics working under applicable mechanical codes, including SMACNA duct construction standards. Shut down the air handler and close the system before cutting into existing ductwork or securing this fitting. Seal all joints with listed duct mastic or UL 181-rated tape to meet energy code requirements. Sheet metal screws, drive cleats, or S-slip connectors are typically used to secure rectangular connections.
