Southwark Metal 90-24GA_4IN Round Duct Elbow 90 Degree 24 Gauge

Product Description

The SOUTHWARK METAL 90-24GA_4IN is a 90-degree round sheet metal duct elbow fabricated from hot dip galvanized steel at 24 gauge material thickness. It is used to change airflow direction in residential and light commercial HVAC duct systems. The elbow measures 4 inches in diameter on both the inlet and outlet ends, making it a straight-size fitting with no reduction. Sheet metal workers and HVAC installers use this fitting during duct fabrication and system installation. Galvanized construction resists corrosion and holds up to long-term exposure inside and outside conditioned spaces.

This elbow fits into round duct systems where a 90-degree turn is required. It is suited for supply and return air trunk-and-branch layouts in residential forced-air systems as well as light commercial applications. The 4-inch diameter is a common size for branch runs serving individual registers. HVAC technicians and sheet metal contractors encounter this fitting in both new construction and retrofit ductwork projects that follow ACCA and SMACNA standards.

Key Features

• 90-degree angle for direct right-angle duct transitions
• 24 gauge hot dip galvanized steel construction for corrosion resistance
• 4 inch diameter on both ends — no transition or reduction
• Round profile compatible with standard round duct and fittings
• Meets ACCA and SMACNA applicable standards for duct fabrication

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 4 inch round duct systems built to ACCA and SMACNA standards in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation is performed by licensed sheet metal workers or HVAC technicians. Power down the air handling unit and close any associated dampers before working on the duct system. Secure the elbow with sheet metal screws and seal all joints with UL 181-rated duct tape or mastic sealant per SMACNA guidelines. Follow local mechanical codes for support spacing and hanger requirements.
