Southwark Metal 90-28GA_10IN Round Duct Elbow 28GA 10 in

Product Description

The SOUTHWARK METAL 90-28GA_10IN is a round sheet metal duct elbow designed for 90-degree directional changes in low-pressure HVAC duct systems. Fabricated from hot-dip galvanized steel at 28 gauge, it measures 10 inches in diameter on both the inlet and outlet ends. This fitting is built to ACCA and SMACNA standards, making it a code-consistent choice for residential and light commercial supply or return air ductwork. HVAC sheet metal mechanics and duct installers use this elbow wherever a 90-degree turn is required in a round duct run.

This elbow is suited for round duct systems in forced-air heating and cooling applications. With equal 10-inch diameters on both ends, it maintains consistent airflow cross-section through the turn. It fits into standard round duct assemblies using drive cleats, slip joints, or sheet metal screws per SMACNA installation practices. Typical applications include trunk-to-branch transitions, equipment-side connections, and in-line duct routing changes in residential and light commercial installations.

Key Features

• 90-degree angle for standard directional duct changes
• Hot-dip galvanized steel construction resists corrosion in conditioned air environments
• 28 gauge material thickness meets SMACNA and ACCA duct fabrication standards
• Equal 10-inch inlet and outlet diameters maintain consistent duct sizing through the elbow
• Round profile compatible with standard round duct fittings and connectors

Compatibility

Designed as an OEM-style replacement and new-construction fitting for 10-inch round duct systems fabricated and installed to ACCA and SMACNA standards.

Installation Notes

Installation should be performed by a qualified HVAC technician or licensed sheet metal mechanic in accordance with SMACNA duct construction standards and local mechanical codes. Secure connections using drive cleats, slip couplings, or sheet metal screws, and seal all joints with approved duct mastic or foil-backed tape per code requirements. Shut down the air handling system and verify the system is de-energized before making any duct modifications. Do not over-compress the gauge material when fastening, as deformation can affect airflow performance.
