Southwark Metal 13_18X10 Trunk Duct Angle 18x10 45 Degree

Product Description

The SOUTHWARK METAL 13_18X10 is a flat Broadway rectangular trunk duct angle designed for sheet metal ductwork fabrication and installation. Built from hot dip galvanized steel, this 45-degree angle fitting measures 18 inches by 10 inches and is used to redirect airflow in rectangular trunk duct systems. It meets ACCA and SMACNA standards, making it appropriate for residential and light commercial HVAC installations. Sheet metal mechanics and HVAC installers use this fitting when routing supply or return trunk lines around structural obstacles or transitioning duct direction within a system.

This trunk duct angle is suited for rectangular duct systems in forced-air heating and cooling applications. The flat Broadway profile is a common style in residential new construction and retrofit ductwork where a 45-degree offset is needed along a trunk line run. It is fabricated for standard sheet metal duct assemblies and is compatible with conventional rectangular duct construction methods per SMACNA guidelines.

Key Features

• 45-degree angle for directional changes in rectangular trunk duct runs
• Hot dip galvanized steel construction for corrosion resistance in HVAC environments
• Flat Broadway rectangular profile fits standard trunk duct fabrication methods
• Meets ACCA and SMACNA applicable standards
• Consistent 18 x 10 inch sizing on both Size A and Size B dimensions

Compatibility

Designed as an OEM-style sheet metal fitting for use with rectangular trunk duct systems fabricated and installed per SMACNA and ACCA standards in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation should be performed by a qualified sheet metal mechanic or licensed HVAC technician. Shut down and lock out the air handling system before modifying or connecting ductwork. Secure fittings with sheet metal screws and seal all joints with UL 181-rated duct sealant or mastic per local mechanical code requirements. Follow SMACNA duct construction standards for proper support and connection methods.
