Southwark Metal WSJ_24X3-1/4X14 Duct Wall Stack

Product Description

The SOUTHWARK METAL WSJ_24X3-1/4X14 is a sheet metal duct wall stack designed for supply air distribution in residential and light commercial HVAC systems. Constructed from hot dip galvanized steel, this wall stack measures 3-1/4 inches by 14 inches by 24 inches and provides a rigid, corrosion-resistant duct section for routing conditioned air through wall cavities. HVAC installers and sheet metal contractors rely on this type of fitting to connect trunk ducts to floor or wall registers in forced-air heating and cooling systems.

Wall stack fittings like the WSJ_24X3-1/4X14 are commonly used in new construction and retrofit applications where space between wall studs is limited. The 3-1/4 inch depth is a standard dimension that fits within a nominal 2x4 wall cavity, making it well suited for residential forced-air systems using gas furnaces, heat pumps, or air handlers. Sheet metal duct installers use this component as part of a complete supply air trunk-and-branch layout.

Key Features

• Hot dip galvanized steel construction resists corrosion in conditioned spaces
• 3-1/4 inch depth fits standard 2x4 residential wall cavities
• 24 inch length provides a full wall-height duct section in typical residential framing
• Meets ACCA and SMACNA applicable standards for sheet metal ductwork
• Rigid construction maintains duct geometry under normal system static pressure

Compatibility

Designed as an OEM-style sheet metal wall stack fitting for residential and light commercial forced-air HVAC duct systems built to ACCA and SMACNA standards.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal contractor. Shut down and lock out the air handling system before making duct connections. Seal all joints with listed duct sealant or mastic and secure with sheet metal screws per SMACNA installation guidelines. Verify that duct sizing and layout comply with ACCA Manual D requirements for the system design.
