Southwark Metal WS16_3-1/4X10 Duct Elbow 90 Degree 3-1/4x10

Product Description

The SOUTHWARK METAL WS16_3-1/4X10 is a 90-degree shortway sheet metal duct elbow designed for vertical wall stack applications in residential and light commercial HVAC ductwork. Fabricated from hot dip galvanized steel, this fitting measures 3-1/4 inches by 10 inches on both the inlet and outlet (Size A and Size B), making it a symmetrical fitting suited for tight-space directional changes. The shortway geometry reduces the turning radius, which is critical when routing ductwork through wall cavities or confined framing bays. HVAC sheet metal mechanics and duct installers use this elbow to redirect conditioned airflow within wall stack systems without sacrificing structural integrity.

This elbow is intended for vertical wall stack duct systems where a 90-degree directional change is required in a space-constrained installation. The 3-1/4 inch by 10 inch rectangular profile is a standard wall stack dimension commonly found in residential forced-air heating and cooling systems. The shortway design keeps the fitting compact along the short axis of the duct, making it the correct choice when ceiling height, stud spacing, or framing depth limits the available turning room.

Key Features

• 90-degree turn angle for direct right-angle duct transitions
• Shortway design reduces fitting depth for use in tight wall cavities
• Hot dip galvanized steel construction resists corrosion in conditioned and unconditioned spaces
• Symmetrical 3-1/4 inch by 10 inch inlet and outlet sizing for straightforward installation
• Meets ACCA and SMACNA applicable standards for sheet metal duct fabrication
• Vertical wall stack configuration for standard residential duct routing

Compatibility

Designed as an OEM-style sheet metal fitting for vertical wall stack duct systems using 3-1/4 inch by 10 inch rectangular duct sections in residential forced-air HVAC installations.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal mechanic. Shut down the air handling system before modifying or connecting ductwork. Secure the elbow to adjoining duct sections using sheet metal screws and seal all joints with UL 181-rated mastic or approved foil tape per SMACNA guidelines. Verify that the fitting orientation matches the intended airflow direction before fastening.
