Southwark Metal 13_10X8 Trunk Duct Angle 10x8 45 Degree

Product Description

The SOUTHWARK METAL 13_10X8 is a sheet metal trunk duct angle fitting designed for rectangular HVAC ductwork systems. Constructed from hot dip galvanized steel, this fitting delivers a 45-degree directional change in a flat, Broadway-style configuration with a radius throat. The radius throat geometry reduces turbulence at the turn, supporting better airflow efficiency through the trunk duct run. It is sized at 10 inches x 8 inches on both the inlet and outlet, making it a same-size transition angle. HVAC sheet metal installers and duct fabricators work with this fitting in forced-air system rough-ins and duct layout applications.

This duct angle fitting is intended for use in residential and light commercial forced-air HVAC installations where a 45-degree trunk duct turn is required. The flat Broadway profile suits low-clearance ceiling or floor plenum installations. The same-dimension inlet and outlet sizing at 10 inches x 8 inches on both ends allows it to continue a trunk run at a 45-degree angle without reducing the duct cross-section. It is fabricated to ACCA and SMACNA applicable standards, making it appropriate for code-compliant duct system installations.

Key Features

• 45-degree trunk duct angle for directional duct routing without reducing cross-section
• Flat Broadway configuration suited for low-clearance installation environments
• Radius throat design reduces airflow turbulence at the turn
• Hot dip galvanized steel construction for corrosion resistance in conditioned air applications
• Consistent 10 inches x 8 inches sizing on both inlet and outlet ends
• Fabricated to ACCA and SMACNA standards for code-compliant duct systems

Compatibility

Designed as an OEM-style sheet metal fitting for rectangular trunk duct systems requiring a 45-degree angle change at 10 inches x 8 inches duct sizing, in compliance with ACCA and SMACNA ductwork standards.

Installation Notes

This fitting is installed by licensed HVAC technicians or sheet metal workers during duct system fabrication and rough-in. Power down the air handling system before working on any duct section connected to an active system. Seal all joints with UL 181-rated duct mastic or approved foil tape per local mechanical code requirements. Follow SMACNA installation guidelines for fastener spacing and support hanger placement on trunk duct runs.
