Southwark Metal WS13_3-1/4X10 Duct Angle 45 Degree

Product Description

The SOUTHWARK METAL WS13_3-1/4X10 is a 45-degree sheet metal duct angle used to transition or offset rectangular duct runs in residential and light commercial HVAC systems. Fabricated from hot dip galvanized steel, this fitting measures 3-1/4 inches x 10 inches on both the inlet and outlet ends, making it a straight-size connection with no reduction. It is rated for flat, Broadway, longway, and wall stack duct configurations, giving installers flexibility across multiple layout types. HVAC sheet metal mechanics and duct installers are the primary trades for this fitting.

This duct angle is suited for low-profile wall stack installations, floor duct systems, and standard trunk-and-branch layouts where a 45-degree offset is required. The 3-1/4 x 10 inch cross-section is a common wall stack size found in residential construction, fitting inside standard 2x4 and 2x6 framed wall cavities. It is appropriate for supply-side duct systems in forced-air heating and cooling applications built to ACCA and SMACNA standards.

• Dual 3-1/4 x 10 inch openings — no size reduction from inlet to outlet

Installation Notes

Installation should be performed by a licensed sheet metal mechanic or HVAC technician. Power down the air handling unit and close the system dampers before modifying any duct section. Secure the fitting with sheet metal screws and seal all joints with UL 181-rated duct mastic or approved foil tape per SMACNA guidelines. Wear cut-resistant gloves when handling raw sheet metal edges.
