Southwark Metal 1140R1210 Vertical 90 Radius Elbow 12x10

Product Description

The SOUTHWARK METAL 1140R1210 is a vertical 90-degree radius elbow sheet metal duct fitting sized at 12 inches by 10 inches. It is designed to redirect airflow at a 90-degree angle within low-pressure sheet metal duct systems. The radius-style throat provides smoother airflow transition compared to a square-throat elbow, reducing turbulence and static pressure loss in the run. HVAC installers and sheet metal workers use this fitting in forced-air residential and light commercial duct systems where a vertical directional change is required.

This fitting is suited for supply or return duct branches that require a vertical 90-degree turn in rectangular sheet metal ductwork. The 12-inch by 10-inch opening size matches standard duct dimensions commonly found in residential forced-air heating and cooling installations. It is typically installed inline with matching rectangular duct sections and is field-connected using drive cleats, S-cleats, or equivalent sheet metal fastening methods per local mechanical code requirements.

Key Features

• Vertical orientation 90-degree elbow for directional duct routing
• Radius throat design reduces airflow turbulence and pressure drop compared to square-throat elbows
• 12-inch by 10-inch duct opening fits standard rectangular sheet metal duct sizing
• Sheet metal construction for compatibility with standard low-pressure forced-air duct systems
• Compatible with drive cleat and S-cleat connection methods standard to rectangular duct assembly

Compatibility

Designed as an OEM-style sheet metal duct fitting for use with standard 12-inch by 10-inch rectangular duct systems in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation is performed by licensed sheet metal workers or HVAC technicians in accordance with SMACNA duct construction standards and local mechanical codes. Shut down and lock out the air handler or furnace before making any duct connections. Secure the fitting to adjacent duct sections using drive cleats and S-cleats, and seal all joints with UL 181-rated duct sealant or foil tape as required by code. Do not exceed the pressure class rating of the surrounding duct system.
