Southwark Metal 13_26X8 Trunk Duct Angle 26x8 in 45 Deg

Product Description

The SOUTHWARK METAL 13_26X8 is a sheet metal trunk duct angle fitting used in forced-air HVAC duct systems to redirect airflow at a 45-degree turn. Fabricated from hot dip galvanized steel, this Broadway-style flat fitting features a radius throat design that promotes smooth airflow transition through the turn, reducing turbulence and pressure loss. Both inlet and outlet dimensions are 26 inches by 8 inches, making this a same-size transition angle. It is installed by sheet metal workers and HVAC technicians during ductwork fabrication or renovation in residential and light commercial systems.

This trunk duct angle is suited for rectangular trunk duct systems where a 45-degree directional change is required while maintaining the same duct cross-section. The flat Broadway configuration is commonly used in low-clearance installations such as between floor joists or in tight mechanical spaces. The radius throat geometry is consistent with ACCA and SMACNA duct construction standards, making it appropriate for systems designed to those specifications. HVAC installers and sheet metal fabricators typically use this fitting during new construction or duct replacement work.

Key Features

• 45-degree angle for directional trunk duct transitions without size change
• Hot dip galvanized steel construction for corrosion resistance in conditioned air applications
• Broadway flat profile suits low-clearance installation environments
• Radius throat design reduces turbulence and static pressure loss at the turn
• Consistent with ACCA and SMACNA duct fabrication standards
• Same inlet and outlet size: 26 inches by 8 inches on both ends

Compatibility

Designed as an OEM-style sheet metal fitting for rectangular trunk duct systems requiring a 45-degree flat Broadway angle at a 26-inch by 8-inch duct size, in applications built to ACCA and SMACNA standards.

Installation Notes

Installation is performed by licensed sheet metal workers or HVAC technicians following SMACNA duct construction guidelines. Power down the air handling system before connecting or sealing ductwork. Secure the fitting to adjacent duct sections using sheet metal screws and seal all joints with listed duct sealant or foil tape per applicable mechanical codes. Do not force-fit the angle into undersized openings, as distortion of the throat radius will degrade airflow performance.
