Southwark Metal WS15_3-1/4X14 Duct Angle 3-1/4x14

Product Description

The SOUTHWARK METAL WS15_3-1/4X14 is a 45-degree shortway duct angle fabricated from hot dip galvanized steel, designed for vertical wall stack applications in residential and light commercial HVAC duct systems. This fitting transitions airflow at a 45-degree angle along the short dimension of the duct, making it the correct choice when vertical direction changes are required in tight wall cavity installations. The inlet and outlet both measure 3-1/4 inches x 14 inches, maintaining a consistent cross-section through the turn. HVAC sheet metal installers use this fitting where duct runs must redirect within wall stack assemblies without reducing flow area.

This duct angle is suited for wall stack installations in residential forced-air systems where duct routing must navigate framing constraints. The shortway orientation addresses direction changes along the 3-1/4-inch dimension, keeping the fitting compact within standard stud-bay widths. It is appropriate for supply-air duct systems routed vertically through interior or exterior walls. Installers working to ACCA Manual D duct design guidelines or SMACNA duct construction standards will find this fitting built to those applicable standards.

Key Features

• 45-degree angle for shortway, vertical direction changes in wall stack duct runs
• Hot dip galvanized steel construction for corrosion resistance in HVAC environments
• Consistent 3-1/4 inches x 14 inches cross-section on both Size A and Size B ends — no reduction in flow area
• Meets ACCA and SMACNA applicable standards for duct construction and installation
• Shortway orientation fits within standard wall cavity widths

Compatibility

Designed for use in residential and light commercial wall stack duct systems using 3-1/4 inches x 14 inches rectangular duct. Compatible with ACCA- and SMACNA-compliant sheet metal duct assemblies of matching cross-section.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal installer in accordance with SMACNA duct construction standards and local mechanical code requirements. Power down the air handling unit and confirm the system is depressurized before fitting connections are made or disturbed. Secure all duct joints with appropriate fasteners and seal with listed duct sealant or mastic per local code — do not rely on tape alone for pressure-class applications. Verify that the shortway orientation aligns with the intended direction of the turn before final fastening.
