Southwark Metal 1140R2010 Vertical 90 Radius Elbow 20x10

Product Description

The SOUTHWARK METAL 1140R2010 is a 20x10 inch vertical 90-degree radius elbow designed for sheet metal ductwork installations. This fitting redirects airflow at a 90-degree angle using a swept radius geometry, which reduces turbulence and static pressure loss compared to square-throat elbows. It is a core component in trunk-and-branch and plenum-style HVAC distribution systems. HVAC sheet metal contractors and ductwork installers use this fitting in both new construction and replacement applications where a smooth directional change is required in a vertical duct run.

This elbow is suited for residential and light commercial forced-air systems where a 20x10 inch duct cross-section is specified. The radius design supports efficient airflow transition in vertical trunk lines or branch takeoffs that require a 90-degree directional change. It is commonly installed in attic, basement, and mechanical room duct runs where clearance and airflow performance must both be managed.

Key Features

• 90-degree vertical radius elbow geometry reduces turbulence and static pressure drop vs. square-throat fittings
• 20x10 inch duct cross-section fits standard rectangular duct trunk and branch layouts
• Sheet metal construction provides structural rigidity for long-term duct system integrity
• Radius throat design supports balanced airflow distribution across connected duct runs

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 20x10 inch rectangular sheet metal duct systems in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation is performed by licensed sheet metal contractors or qualified HVAC technicians. Power down the air handler or furnace and ensure the blower is off before cutting into or connecting to existing ductwork. Seal all joints with UL 181-listed mastic or metal tape per local mechanical codes. Verify fitting orientation and airflow direction before final fastening.
