Southwark Metal WS15_3-1/4X12 Duct Angle 3.25x12 in

Product Description

The SOUTHWARK METAL WS15_3-1/4X12 is a 45-degree sheet metal duct angle fitting designed for shortway, vertical wall stack duct applications. Fabricated from hot dip galvanized steel, this fitting connects 3.25-inch x 12-inch duct to 3.25-inch x 12-inch duct at a 45-degree turn. It is used to route rectangular ductwork through wall cavities where space constraints require a shortway bend orientation. HVAC installers and sheet metal mechanics rely on this type of fitting to maintain airflow direction changes within low-profile residential and light commercial duct systems.

This duct angle fitting is suited for vertical wall stack installations in residential forced-air heating and cooling systems. The shortway orientation makes it appropriate for tight wall cavity runs where the duct must change direction along its short dimension. It meets ACCA and SMACNA standards, making it compatible with duct systems designed and installed to those specifications. Installers working with standard 3.25-inch x 12-inch rectangular wall stack duct will find this fitting dimensionally matched for a direct connection.

Key Features

• 45-degree angle for directional duct transitions in wall stack systems
• Shortway, vertical orientation for low-profile wall cavity installations
• Hot dip galvanized steel construction for corrosion resistance in HVAC duct applications
• Connects 3.25-inch x 12-inch duct to 3.25-inch x 12-inch duct — no reduction in cross-section
• Meets ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style sheet metal fitting for residential and light commercial forced-air duct systems using standard 3.25-inch x 12-inch rectangular wall stack duct, installed to ACCA and SMACNA standards.

Installation Notes

Sheet metal duct fittings of this type are installed by licensed HVAC technicians or journeyman sheet metal mechanics. Shut down the air handling system before modifying or extending ductwork. Secure all joints with sheet metal screws and seal with UL 181-rated mastic or foil tape per local mechanical code and SMACNA guidelines. Follow ACCA Manual D duct design requirements to ensure the fitting is placed correctly within the duct layout to maintain proper airflow.
