Southwark Metal WS15_3-1/4X10 Duct Angle 3-1/4x10 in

Product Description

The SOUTHWARK METAL WS15_3-1/4X10 is a 45-degree sheet metal duct angle fitting designed for shortway, vertical wall stack duct installations. Fabricated from hot dip galvanized steel, this fitting connects two 3-1/4 x 10 inch duct sections at a 45-degree turn, maintaining consistent cross-sectional dimensions on both ends. It is used in residential and light commercial forced-air HVAC systems where space constraints require a low-profile shortway turn. HVAC sheet metal technicians and duct installers work with this fitting during new construction and retrofit ductwork runs.

This fitting is specifically suited for vertical wall stack applications where the duct transitions at a 45-degree angle within a wall cavity or framed chase. The shortway orientation keeps the fitting compact along the short dimension of the rectangular duct profile, making it a common choice in tight framing conditions. The 3-1/4 x 10 inch size is a standard floor-register duct dimension widely used in residential forced-air systems. Compliance with ACCA and SMACNA standards ensures dimensional and performance consistency within engineered duct systems.

Key Features

• 45-degree angle for shortway vertical wall stack duct routing
• Hot dip galvanized steel construction for corrosion resistance in interior duct applications
• Identical inlet and outlet size: 3-1/4 x 10 inches on both ends
• Meets ACCA and SMACNA applicable standards
• Shortway profile minimizes space requirements within wall cavities and framed chases

Compatibility

Designed as an OEM-style replacement and new-construction fitting for standard 3-1/4 x 10 inch rectangular sheet metal duct systems in residential and light commercial forced-air HVAC installations.

Installation Notes

Installation should be performed by a qualified HVAC technician or licensed sheet metal contractor in accordance with SMACNA duct construction standards and local mechanical codes. Power down the air handling system before connecting or modifying ductwork. Secure all joints with approved sheet metal screws and seal with UL 181-rated mastic or metal-backed tape per applicable code. Verify duct dimensions and fitting orientation before fastening to avoid misalignment within the wall cavity.
