Southwark Metal WSJ_60X3-1/4X12 Duct Wall Stack

Product Description

The SOUTHWARK METAL WSJ_60X3-1/4X12 is a sheet metal duct wall stack designed for residential and light commercial forced-air HVAC distribution systems. Fabricated from hot dip galvanized steel, this wall stack measures 3.25 inches by 12 inches by 60 inches and provides a rigid, corrosion-resistant airflow pathway routed through interior wall cavities. It connects supply air from the plenum or trunk line to floor or wall registers. HVAC sheet metal installers and mechanical contractors handle this component as part of a complete duct distribution rough-in.

Wall stacks like this one are used in new construction and renovation projects where duct runs must travel vertically within stud-bay wall cavities. The 3.25 x 12 inch cross-section fits standard framing layouts and accommodates typical residential register sizes. This unit is 60 inches in length, suitable for single-story wall runs or cut-to-length applications on the job site.

Key Features

• Hot dip galvanized steel construction resists corrosion in conditioned and unconditioned spaces
• 3.25 x 12 x 60 inch dimensions fit standard stud-bay rough-in layouts
• Rigid sheet metal build maintains airflow cross-section without collapse
• Meets ACCA and SMACNA applicable standards for duct fabrication
• Can be field-cut to required length during installation

Compatibility

Designed as an OEM-style sheet metal duct component for use in residential and light commercial forced-air supply duct systems requiring a 3.25 x 12 inch wall stack configuration.

Installation Notes

Wall stacks are installed by licensed HVAC technicians or sheet metal mechanics during duct rough-in. Power down the air handler and close the gas supply before working on any connected duct system. Seal all joints with UL-listed mastic or foil tape per SMACNA and local mechanical code requirements. Use appropriate tin snips and seaming tools when cutting or connecting to adjacent fittings.
