Southwark Metal 15S_20X10 Trunk Duct Angle 20x10 in

Product Description

The SOUTHWARK METAL 15S_20X10 is a sheet metal trunk duct angle fitting used in forced-air HVAC duct systems to redirect airflow through a 45-degree turn. Fabricated from hot dip galvanized steel, this fitting features a shortway, vertical, square throat configuration measuring 20 inches x 10 inches on both the inlet and outlet. The square throat design maintains a consistent cross-section through the turn, reducing turbulence and pressure loss in rectangular trunk duct runs. HVAC sheet metal mechanics and duct installers use this fitting during new construction and retrofit duct fabrication work.

This fitting is suited for rectangular trunk duct systems in residential and light commercial forced-air applications. The shortway orientation makes it appropriate for installations where horizontal clearance is limited and the turn must be made within a tighter radius relative to the duct width. Both inlet and outlet dimensions are 20 inches x 10 inches, making this a straight-size fitting with no reduction. It is fabricated to meet ACCA and SMACNA duct construction standards, which are the primary design and fabrication references for commercial and residential sheet metal duct systems.

Key Features

• 45-degree shortway trunk duct angle fitting for rectangular duct runs
• Hot dip galvanized steel construction for corrosion resistance in HVAC duct applications
• Square throat configuration maintains consistent cross-section through the turn
• Vertical, shortway orientation for installations with limited clearance
• Uniform 20 inches x 10 inches inlet and outlet — no size reduction
• Fabricated to ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style sheet metal fitting for rectangular trunk duct systems built to ACCA and SMACNA standards, with 20 inches x 10 inches duct connections on both ends.

Installation Notes

Installation should be performed by a licensed sheet metal mechanic or HVAC technician. Shut down the air handling unit and lock out power before connecting or modifying duct sections. Secure the fitting to adjoining duct sections using sheet metal screws and seal all joints with UL 181-rated duct sealant or mastic in accordance with local mechanical codes and SMACNA guidelines. Do not compress or distort the fitting during installation, as deformation will affect airflow performance.
