Southwark Metal 15_25X10 Trunk Duct Angle 25x10 45 Degree

Product Description

The SOUTHWARK METAL 15_25X10 is a sheet metal trunk duct angle fitting designed for directional transitions in forced-air HVAC duct systems. Fabricated from hot dip galvanized steel, this fitting delivers a 45-degree shortway turn with a vertical, radius throat geometry. The radius throat reduces turbulence and pressure drop through the turn compared to square-throat alternatives. Frame size is 25 inches x 10 inches on both the inlet and outlet, making it a same-size transition. HVAC sheet metal installers and duct fabricators use this fitting when laying out trunk duct systems that require a 45-degree directional change in tight or constrained spaces.

This duct angle fitting is suited for residential and light commercial forced-air supply or return trunk duct installations. The shortway orientation makes it applicable where the turn must be made across the short dimension of the duct, and the vertical radius throat design supports better airflow performance through the fitting. Fabricated to ACCA and SMACNA standards, it is appropriate for systems designed and installed in compliance with those guidelines. Both the inlet and outlet measure 25 inches x 10 inches, so no transition or reducer is required at either end when connecting to matching trunk sections.

Key Features

• 45-degree trunk duct angle for directional routing in forced-air systems
• Shortway, vertical orientation with radius throat for reduced airflow turbulence
• Hot dip galvanized steel construction for corrosion resistance in typical HVAC environments
• Same-size inlet and outlet: 25 inches x 10 inches on both ends
• Fabricated to ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style sheet metal fitting for use with 25 inches x 10 inches rectangular trunk duct in residential and light commercial forced-air HVAC installations built to ACCA and SMACNA standards.

Installation Notes

Sheet metal duct fittings of this type are installed by licensed HVAC technicians or journeyman sheet metal workers. Power down the air handling unit and verify the system is de-energized before working inside the duct system. Secure all duct connections with sheet metal screws and seal joints with UL 181-listed mastic or foil tape per local mechanical code and SMACNA guidelines. Follow ACCA Manual D or equivalent duct design procedures to confirm fitting selection is appropriate for the system layout.
