Southwark Metal 902024 90 Degree Adjustable Elbow 20 Inches 24 Gauge Galvanized Steel Round Duct Elbow

Product Description

The Southwark Metal 902024 is a 90 degree adjustable elbow designed for round duct systems in residential and commercial HVAC applications. This fitting measures 20 inches in diameter and is fabricated from 24 gauge hot dipped galvanized steel meeting ASTM A653 CS Type B standards. It is built for HVAC installers, sheet metal contractors, and mechanical contractors who need a reliable, code-grade fitting for duct transitions and direction changes. The 90 degree bend angle makes it a go-to component when ductwork must change direction in tight mechanical spaces, attics, basements, or utility rooms. The galvanized coating provides corrosion resistance and extends the service life of the fitting in both conditioned and unconditioned spaces. This elbow features a crimped male connection on one end and a straight female connection on the other, making it compatible with standard round duct and fittings. The 1 inch crimp length ensures a secure, consistent fit. The 1/2 inch overlap is designed specifically for riveting using 1/8 inch rivets, giving installers a solid mechanical connection that holds up under system pressure and vibration. This fitting ships as a 4-piece assembly, following the standard configuration for round duct elbows 3 inches through 20 inches in diameter. Pieces are assembled on the job site, reducing shipping volume while maintaining the full structural integrity of the finished fitting. Made in the USA, this elbow meets Prop 65 requirements and is sold individually. HVAC techs searching for a large-diameter galvanized steel round duct elbow, 20 inch 90 degree duct fitting, or adjustable elbow for sheet metal ductwork will find this fitting meets the demands of professional-grade installations.
