Southwark Metal 90-30GA_10IN Round Duct Elbow 90 Degree 10 in

Product Description

The SOUTHWARK METAL 90-30GA_10IN is a round 90-degree sheet metal duct elbow fabricated from hot-dip galvanized steel at 30 gauge. It is designed for use in low-pressure ducted HVAC systems where a square-throat or equivalent round-section directional change is required. The elbow measures 10 inches in diameter on both the inlet and outlet, making it a straight-size fitting with no transition. Hot-dip galvanization provides corrosion resistance suited to both supply and return duct applications. HVAC installers and sheet metal contractors use this fitting in residential and light commercial forced-air systems.

This elbow is used in round ductwork runs where a 90-degree direction change is needed without a diameter reduction. Typical applications include trunk-to-branch transitions, mechanical room drops, and rooftop unit connections in residential and light commercial forced-air heating and cooling systems. The 10-inch diameter suits higher-volume branch runs and main trunk segments. Installation conforms to ACCA and SMACNA standards for sheet metal duct fabrication and assembly.

Key Features

• 90-degree turn angle for standard right-angle duct direction changes
• 10-inch inlet and 10-inch outlet diameter — no size transition
• 30-gauge hot-dip galvanized steel construction resists corrosion in conditioned air environments
• Round profile maintains consistent airflow cross-section through the elbow
• Meets ACCA and SMACNA fabrication standards

Compatibility

Designed as an OEM-style replacement and new-construction fitting for round sheet metal duct systems using 10-inch diameter round pipe and fittings per SMACNA and ACCA duct construction guidelines.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Secure the elbow to adjoining duct sections using sheet metal screws and seal all joints with UL 181-rated mastic or foil tape per SMACNA installation standards. Shut down the air handling unit and confirm zero airflow before cutting into or modifying an existing duct system. Support the elbow and adjacent duct runs with hangers sized and spaced in accordance with SMACNA hanger and support guidelines.
