Southwark Metal 10669 Quadrant Damper 9 Inches

Product Description

The SOUTHWARK METAL 10669 is a 9-inch quadrant damper designed for airflow regulation in residential and light commercial duct systems. Quadrant dampers use a rotating blade controlled by an external quadrant handle, allowing technicians to manually set and lock airflow to individual branch runs or zones. This damper is installed in round or rectangular duct takeoffs where balancing or shutoff control is needed. HVAC installers and sheet metal contractors work with this type of component during new construction, system balancing, and duct retrofit projects.

The 10669 is suited for round duct branch balancing applications in forced-air heating and cooling systems. It is typically installed at the trunk-to-branch junction or within a straight duct run where manual volume control is required. The 9-inch size fits standard 9-inch round duct, making it a straightforward fit in common residential trunk-and-branch layouts.

Key Features

• 9-inch diameter fits standard round duct branch runs
• Quadrant handle allows manual airflow adjustment and lockout
• Designed for volume control and balancing in forced-air duct systems
• Sheet metal construction consistent with standard HVAC duct fabrication practices

Compatibility

Designed as an OEM-style replacement and new-installation component for 9-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 sheet metal contractor. The air handling system should be shut down before installing or adjusting the damper. Secure the damper to the duct with sheet metal screws and seal all joints with approved duct tape or mastic per local mechanical code requirements. Do not restrict the quadrant handle range of motion after installation, as this is the primary means of airflow adjustment.
