Southwark Metal 90-24GA_20IN Round Duct Elbow 20 in 24 Ga

Product Description

The SOUTHWARK METAL 90-24GA_20IN is a round sheet metal duct elbow fabricated from hot-dip galvanized steel at 24 gauge. It is designed to redirect airflow at a 90-degree angle within large-diameter round ductwork systems. With a 20-inch diameter on both the inlet and outlet, this elbow suits high-volume commercial and industrial HVAC air distribution layouts. The hot-dip galvanization provides corrosion resistance suitable for supply and return applications. Sheet metal contractors and HVAC installers specify this fitting where durable, code-conforming duct components are required on larger trunk and branch runs.

This elbow is used in round duct systems requiring a 90-degree directional change at 20-inch diameter connections. Its construction meets ACCA and SMACNA standards, making it appropriate for commercial HVAC installations where design and fabrication specifications must align with industry guidelines. Typical applications include large air handler connections, rooftop unit supply plenums, and industrial ventilation runs where consistent gauge and geometry are required throughout the duct system.

Key Features

• 90-degree turn angle for standard directional changes in round duct systems
• 20-inch inlet and outlet diameter for high-volume airflow applications
• 24-gauge hot-dip galvanized steel construction for corrosion resistance and structural rigidity
• Meets ACCA and SMACNA applicable standards for duct fabrication
• Round profile maintains consistent airflow geometry through the elbow

Compatibility

Designed as an OEM-style round duct fitting compatible with 20-inch diameter round ductwork systems fabricated and installed to ACCA and SMACNA standards.

Installation Notes

Installation should be performed by a licensed sheet metal contractor or qualified HVAC technician. Power down and lock out the air handling system before connecting or modifying ductwork. Fittings of this size and gauge typically require sheet metal screws, drive cleats, or standing S-cleats for secure connection, and all joints should be sealed per SMACNA leakage class requirements. Reference applicable local mechanical codes and SMACNA duct construction standards for hanger spacing and support requirements on large-diameter round duct.
