Southwark Metal WSJ_100X3-1/4X12 Duct Wall Stack

Product Description

The SOUTHWARK METAL WSJ_100X3-1/4X12 is a hot dip galvanized steel duct wall stack designed for residential and light commercial HVAC duct distribution systems. Measuring 3.25 inches by 12 inches by 100 inches, this wall stack fitting channels conditioned air from a trunk duct into a wall cavity, connecting to floor or baseboard registers. The hot dip galvanized steel construction provides corrosion resistance suited to the moisture conditions typical in forced-air duct systems. Licensed HVAC technicians and sheet metal contractors install this fitting during new construction or duct replacement work.

Wall stack fittings like this one are used in residential forced-air heating and cooling systems where duct runs travel vertically through interior wall cavities. The 3.25 inch by 12 inch cross-section is a standard duct size compatible with common wall register openings. This fitting is appropriate for low-velocity supply air applications in single-family homes, townhomes, and light commercial spaces where wall-mounted register delivery is specified.

Key Features

• Hot dip galvanized steel construction for corrosion resistance in forced-air duct environments
• 3.25 x 12 x 100 inch profile sized for standard wall cavity duct runs
• Manufactured to ACCA and SMACNA applicable standards for sheet metal ductwork
• Full 100-inch length reduces the need for intermediate splicing in tall wall runs
• Compatible with standard sheet metal fabrication and duct assembly methods

Compatibility

Designed as an OEM-style sheet metal duct component for residential and light commercial forced-air HVAC systems using standard 3.25 inch by 12 inch wall stack duct configurations.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal contractor in accordance with SMACNA duct construction standards and local mechanical codes. Power down the air handling system before cutting into or connecting to any existing ductwork. Seal all joints with UL-listed duct sealant or approved metal tape to meet air leakage requirements. Do not use this fitting in high-pressure or return-air plenum applications unless verified as appropriate by system design.
