Southwark Metal 15_10X8 Trunk Duct Angle 10x8 Shortway 45 Degree

Product Description

The SOUTHWARK METAL 15_10X8 is a 45-degree sheet metal trunk duct angle fitting used in forced-air HVAC duct systems. It is fabricated from hot dip galvanized steel and features a shortway, vertical orientation with a radius throat design. This fitting connects two 10-inch x 8-inch duct sections at a 45-degree turn, maintaining airflow direction changes within a trunk line. Sheet metal workers and HVAC installers use this fitting during new construction and retrofit ductwork applications where a low-profile horizontal turn is required in a confined space.

This duct angle fitting is suited for residential and light commercial forced-air systems where trunk duct routing requires a 45-degree directional change. The shortway configuration keeps the fitting compact along the short dimension of the duct, making it practical in tight ceiling plenums or crawlspaces. The radius throat reduces turbulence and static pressure loss at the turn, supporting efficient airflow distribution. Both inlet and outlet openings measure 10 inches x 8 inches, allowing direct inline installation without transition fittings.

Key Features

• 45-degree angle for directional duct routing in trunk systems
• Shortway, vertical orientation conserves space in tight installations
• Radius throat design reduces turbulence and static pressure loss at the turn
• Hot dip galvanized steel construction resists corrosion in unconditioned spaces
• Consistent 10-inch x 8-inch opening on both ends eliminates need for transition fittings
• Meets ACCA and SMACNA applicable standards for duct fabrication

Compatibility

Designed as an OEM-style replacement or new-installation fitting for rectangular sheet metal trunk duct systems with a 10-inch x 8-inch cross-section.

Installation Notes

Installation should be performed by a licensed sheet metal worker or HVAC technician following SMACNA duct construction standards and local mechanical codes. Shut down the air handling unit and isolate the duct section before cutting into an existing trunk line. Secure the fitting using standard drive cleats and S-cleats or appropriate sheet metal fasteners, and seal all joints with UL 181-rated mastic or foil tape to maintain system airtightness. Do not force or deform the fitting during installation, as distortion of the radius throat will increase pressure loss.
