Southwark Metal 7353401 Trunk Duct Angle 26x12 45 Degree

Product Description

The SOUTHWARK METAL 7353401 is a shortway trunk duct angle fitting fabricated from hot-dip galvanized steel. It delivers a 45-degree direction change in rectangular sheet metal ductwork and is designed for vertical, square-throat installations. The frame size measures 26 inches x 12 inches on both the inlet and outlet, making it a symmetrical fitting suited for main trunk transitions. This fitting meets ACCA and SMACNA standards, which are the recognized benchmarks for residential and light commercial duct system design and fabrication. Sheet metal contractors and HVAC installers use this component when routing supply or return trunk lines through tight framing cavities where a shortway turn is required.

This duct angle is intended for rectangular sheet metal trunk duct systems in residential and light commercial HVAC installations. The shortway orientation is commonly specified when overhead or in-wall clearance restricts the use of a longway elbow. The 26-inch x 12-inch cross-section fits mid-to-large trunk lines and is appropriate for forced-air systems where the duct layout requires a 45-degree horizontal or vertical offset. Fabricated to ACCA Manual D and SMACNA duct construction guidelines, it integrates directly into standard slip-and-drive or S-cleat assembly methods.

Key Features

• 45-degree angle provides precise directional change in trunk duct runs
• Shortway, vertical, square-throat construction minimizes duct depth requirements in framed cavities
• Hot-dip galvanized steel offers corrosion resistance for long-term duct system performance
• Symmetrical 26 inches x 12 inches inlet and outlet dimensions simplify trunk alignment
• Meets ACCA and SMACNA applicable standards for commercial and residential duct fabrication

Compatibility

Designed as an OEM-style sheet metal component for rectangular trunk duct systems conforming to ACCA and SMACNA fabrication standards. Compatible with standard slip-and-drive and S-cleat connections used in 26-inch x 12-inch rectangular duct assemblies.

Installation Notes

Installation should be performed by a licensed sheet metal contractor or qualified HVAC technician. Shut down the air handling unit and verify the system is de-energized before cutting into or modifying any duct section. Secure the fitting using appropriate S-cleats and drive cleats per SMACNA guidelines, and seal all seams with UL 181-rated mastic or foil tape to maintain system static pressure. Follow local mechanical codes and ACCA Manual D recommendations for fitting placement relative to upstream and downstream duct transitions.
