The SOUTHWARK METAL 90-30GA_6IN is a round sheet metal duct elbow fabricated from hot dip galvanized steel at 30 gauge thickness. It delivers a 90-degree directional change in round duct systems, making it a standard component in residential and light commercial HVAC ductwork installations. With a 6-inch diameter on both the inlet and outlet, this elbow maintains consistent airflow through the duct run. HVAC sheet metal installers and duct fabricators use this fitting where a hard 90-degree turn is required in round duct systems. The hot dip galvanized finish provides corrosion resistance suited for supply and return air applications.
This elbow is used in round duct systems installed in residential and light commercial buildings. It fits into forced-air heating and cooling duct assemblies where a 90-degree change of direction is needed. The 6-inch diameter matches common trunk-to-branch transitions and single-zone supply runs. Sheet metal contractors and HVAC installers will encounter this fitting on jobs requiring code-compliant ductwork per SMACNA and ACCA standards. It connects to standard 6-inch round duct collars, fittings, and boots.
Designed as an OEM-style replacement and standard fitting for 6-inch round duct systems built to SMACNA and ACCA specifications in residential and light commercial forced-air HVAC applications.
This fitting is installed by licensed sheet metal contractors and HVAC technicians working with round duct systems. Power down the air handling unit or furnace before working inside the duct system. Secure the elbow to adjoining duct sections using sheet metal screws and seal all joints with UL 181-rated duct tape or mastic sealant per local mechanical codes. Do not use this fitting in applications requiring spiral lockseam or double-wall duct without verifying gauge compatibility.
