Southwark Metal 44-1_4IN Duct Damper 4 Inch Quad

Product Description

The Southwark Metal 44-1_4IN is a 4-inch quad-style sheet metal duct damper designed for airflow balancing in forced-air HVAC duct systems. Constructed with hot dip galvanized steel blades, this damper provides durable, corrosion-resistant performance in residential and light commercial ductwork applications. The 1-quad configuration allows technicians to manually regulate airflow volume through individual duct branches, helping to balance supply air distribution across zones. It meets applicable standards set by ACCA and SMACNA, making it suitable for code-compliant duct system installations.

This damper is used in rectangular or round sheet metal duct runs where branch-line airflow adjustment is required. It is a common component in new construction duct installations and in retrofit balancing work on existing forced-air heating and cooling systems. HVAC sheet metal installers and service technicians typically install this type of damper during duct fabrication or system commissioning. The 4-inch duct size fits standard small-diameter branch runs serving individual rooms or zones.

Key Features

• Hot dip galvanized steel blade construction for corrosion resistance in duct environments
• 1-Quad damper type for manual airflow volume control
• 4-inch duct size fits standard small-diameter branch duct runs
• Meets ACCA and SMACNA applicable standards for duct system components
• Supports airflow balancing across multi-zone forced-air systems

Compatibility

Designed as an OEM-style replacement or new-installation component for 4-inch sheet metal duct branch runs in residential and light commercial forced-air HVAC systems.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal installer. The duct system should be de-energized and the air handler shut down before installing or adjusting dampers in the duct run. Secure the damper according to SMACNA duct construction standards using appropriate sheet metal fasteners. Verify blade position and airflow direction after installation during system commissioning.
