Southwark Metal 1141R2610 Duct Angle Shortway 26x10 45 Degree

Product Description

The SOUTHWARK METAL 1141R2610 is a hot-dip galvanized steel trunk duct angle fitting designed for shortway, vertical, square-throat transitions in sheet metal ductwork systems. Sized at 26 inches x 10 inches on both the inlet and outlet, this 45-degree angle fitting handles directional changes in low-pressure supply or return trunk duct runs. It is fabricated to meet ACCA and SMACNA standards, making it a compliant choice for commercial and residential forced-air systems. HVAC sheet metal technicians and duct installers use this fitting where a shortway turn is required without sacrificing structural integrity or airflow geometry.

This fitting is suited for rectangular trunk duct systems in residential and light commercial HVAC installations where 45-degree shortway turns are required. The square-throat, vertical orientation accommodates tight mechanical room layouts and inline trunk transitions. It is typically installed in supply or return duct mains fabricated from galvanized sheet metal, and it integrates directly with standard 26 x 10 inch rectangular duct sections. Installers working on forced-air furnace and air handler systems will find this fitting appropriate for runs requiring a low-profile directional change.

Key Features

• 45-degree shortway angle for compact directional changes in rectangular trunk duct
• Hot-dip galvanized steel construction for corrosion resistance in HVAC environments
• Square-throat, vertical profile minimizes turbulence in shortway configurations
• Meets ACCA and SMACNA fabrication and performance standards
• Consistent 26 x 10 inch sizing on both Size A and Size B connections for straight trunk integration

Compatibility

Designed as an OEM-style sheet metal fitting compatible with standard 26 x 10 inch rectangular trunk duct systems fabricated to ACCA and SMACNA specifications.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal mechanic. Power down the air handling equipment before making any duct modifications. Secure the fitting using drive cleats, S-cleats, or screws per SMACNA guidelines, and seal all joints with mastic or UL 181-listed tape to maintain system pressure integrity. Verify duct system design with a Manual D or equivalent load calculation before finalizing fitting placement.
