Southwark Metal 90-30GA_7IN Round Duct Elbow 90 Degree 7 in

Product Description

The SOUTHWARK METAL 90-30GA_7IN is a 90-degree round sheet metal duct elbow designed for use in forced-air duct systems. Fabricated from hot-dip galvanized steel at 30 gauge, this elbow provides a reliable directional change in round ductwork runs. With a 7-inch diameter on both the inlet and outlet, it maintains consistent airflow cross-section through the turn. HVAC installers and sheet metal contractors use this fitting where duct routing requires a sharp 90-degree direction change without reducing duct size. The galvanized finish resists corrosion in both supply and return air applications.

This elbow is suited for residential and light commercial HVAC duct installations where round ductwork is the primary distribution method. It fits into standard round duct systems where a 90-degree turn is needed, such as at equipment plenums, through framing penetrations, or at register drops. The 7-inch diameter is a common size in both supply trunk branch takeoffs and main trunk configurations. Installation is performed by licensed HVAC technicians or sheet metal workers following ACCA and SMACNA duct construction standards.

Key Features

• 90-degree angle for sharp directional changes in round ductwork
• Hot-dip galvanized steel construction for corrosion resistance
• 30 gauge material thickness meets standard duct fabrication requirements
• 7-inch inlet and 7-inch outlet diameter — no reduction through the turn
• Meets ACCA and SMACNA applicable standards for duct construction

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 7-inch round duct systems in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation is typically performed by a licensed HVAC technician or journeyman sheet metal worker. Power down the air handling unit and close the fuel supply valve before working on connected ductwork. Secure the elbow with sheet metal screws and seal all joints with UL-listed duct sealant or foil tape per SMACNA installation standards. Do not use standard duct tape as a primary sealant.
