Southwark Metal WS16_3-1/4X12 Duct Elbow 90 Degree 3-1/4x12

Product Description

The SOUTHWARK METAL WS16_3-1/4X12 is a 90-degree shortway sheet metal duct elbow designed for vertical wall stack applications in residential and light commercial HVAC duct systems. Fabricated from hot dip galvanized steel, this elbow transitions airflow at a right angle in tight spaces where a longway elbow will not fit. The inlet and outlet both measure 3-1/4 inches by 12 inches, making it a symmetrical fitting with no reduction. HVAC installers and sheet metal mechanics use this fitting when routing supply or return ductwork through wall cavities and floor systems. It meets ACCA and SMACNA standards for residential and commercial sheet metal duct fabrication.

This elbow is suited for wall stack duct systems common in residential forced-air heating and cooling installations. The shortway configuration reduces the turning radius, allowing the fitting to be used in confined framing cavities where space is limited. The 3-1/4 inch by 12 inch face is a standard wall stack dimension used with rectangular supply ducts in single-family homes and light commercial buildings. HVAC technicians and sheet metal installers working on new construction or retrofit projects will find this fitting dimensionally consistent with standard wall stack ductwork.

Key Features

• 90-degree shortway elbow for tight-turn applications in wall stack duct systems
• Hot dip galvanized steel construction for corrosion resistance in HVAC environments
• Symmetrical 3-1/4 inch by 12 inch inlet and outlet — no size reduction
• Vertical orientation designed for wall stack installation
• Meets ACCA and SMACNA fabrication standards

Compatibility

Designed as an OEM-style replacement or new-construction fitting for standard 3-1/4 inch by 12 inch rectangular wall stack duct systems in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal mechanic. Power down and lock out the air handling unit before working on connected ductwork. Secure the elbow to adjoining duct sections using sheet metal screws and seal all joints with UL 181-rated mastic or foil tape per local mechanical code requirements. Follow SMACNA installation guidelines for support spacing and joint integrity.
