Southwark Metal SP90-26GA_10IN Spiral Elbow 90 Degree 10 in

Product Description

The SOUTHWARK METAL SP90-26GA_10IN is a 90-degree spiral round sheet metal elbow fabricated from hot dip galvanized steel at 26 gauge. It is designed for use in round duct systems where a 90-degree directional change is required. The spiral seam construction provides consistent roundness and structural rigidity along the fitting body. Both the inlet and outlet diameters measure 10 inches, making this a straight-size elbow with no reduction. HVAC sheet metal mechanics and ductwork installers work with this fitting during system fabrication and installation in forced-air ventilation and air distribution systems.

This elbow is suited for residential and light commercial HVAC ductwork applications where round spiral duct is the primary distribution method. It connects directly to 10-inch spiral or snap-lock round duct and is installed at air handler outlets, branch takeoffs, and trunk-to-branch transitions that require a 90-degree turn. Fabrication and installation practices for this fitting follow ACCA and SMACNA standards, which govern duct construction, leakage classification, and fitting geometry in forced-air systems.

Key Features

• 90-degree elbow angle for a full quarter-turn directional change in round duct runs
• 10-inch inlet and outlet diameter — no reduction, straight-size fitting
• 26-gauge hot dip galvanized steel construction for corrosion resistance
• Spiral round design provides uniform cross-section and consistent fitment with spiral duct
• Meets ACCA and SMACNA applicable standards for duct fitting construction

Compatibility

Designed for use with 10-inch round spiral and snap-lock duct systems in forced-air HVAC applications. Fabricated and installed in accordance with ACCA and SMACNA standards for sheet metal duct fittings.

Installation Notes

Installation should be performed by a licensed sheet metal mechanic or HVAC technician following SMACNA duct construction guidelines. Power down the air handling unit and isolate the duct section before fitting installation. Secure the elbow to adjoining duct with sheet metal screws and seal all joints with UL 181-listed duct tape or mastic sealant per local mechanical code requirements. Do not force or distort the fitting during assembly, as deformation will affect airflow performance and joint integrity.
