Southwark Metal 90-24GA_16IN Round Duct Elbow 90 Degree 24 Gauge

Product Description

The SOUTHWARK METAL 90-24GA_16IN is a round sheet metal duct elbow fabricated from hot dip galvanized steel at 24 gauge thickness. It provides a 90-degree directional change in round duct runs and is sized at 16 inches diameter on both the inlet and outlet. This fitting is built to ACCA and SMACNA standards, making it a code-appropriate choice for commercial and residential HVAC duct systems. Sheet metal workers and HVAC installers use this elbow when routing supply or return air ductwork around structural obstructions or when transitioning duct direction within an air distribution system.

This elbow is suited for round duct installations in residential and light commercial HVAC systems where a 90-degree turn is required. The 16-inch diameter on both ends allows for straight-in installation within an existing 16-inch round duct run without reducers or adapters. Applications include supply trunk branches, return air plenums, and inline duct routing in forced-air systems. Fabricated to SMACNA and ACCA duct construction standards, this fitting is commonly specified on engineered duct layouts and field-fabricated systems alike.

Key Features

• 90-degree angle provides a full directional change in round duct runs
• 16-inch inlet and 16-inch outlet diameter — no reducer needed in matching duct runs
• 24 gauge hot dip galvanized steel construction for corrosion resistance and rigidity
• Meets ACCA and SMACNA applicable standards for duct construction
• Round profile compatible with standard round duct fittings and collars

Compatibility

Designed as an OEM-style sheet metal fitting for use in standard 16-inch round duct systems built to SMACNA and ACCA duct construction guidelines.

Installation Notes

Installation is performed by licensed sheet metal workers or HVAC technicians. Shut down the air handling system before connecting or disconnecting duct fittings. Secure the elbow with sheet metal screws and seal all joints with UL 181-listed duct sealant or mastic per SMACNA installation standards. Do not use this fitting on systems requiring a different gauge specification without verifying pressure class compatibility.
