Southwark Metal 44-1_8IN Sheet Metal Duct Damper 8 in

Product Description

The SOUTHWARK METAL 44-1_8IN is a 1-quad sheet metal duct damper sized for 8-inch round ductwork. It is used to regulate or shut off airflow in forced-air HVAC distribution systems. The blade is constructed from hot dip galvanized steel, providing corrosion resistance suited to both supply and return air applications. Built to ACCA and SMACNA standards, this damper is designed for installation by sheet metal contractors, HVAC technicians, and mechanical trades professionals working on residential and light commercial duct systems.

This damper is appropriate for 8-inch round duct runs in forced-air heating and cooling systems. The 1-quad configuration makes it a practical choice for balancing airflow in branch duct installations, zone control setups, or any application where manual air volume regulation is required. It fits within standard sheet metal duct assemblies and is sized to match conventional 8-inch round spiral or snap-lock duct.

Key Features

• Hot dip galvanized steel blade for corrosion resistance in air distribution environments
• 1-quad style damper for manual airflow balancing in round duct branches
• Sized for 8-inch round ductwork to match standard residential and light commercial duct dimensions
• Meets ACCA and SMACNA applicable standards for sheet metal duct components

Compatibility

Designed as an OEM-style replacement or new-installation damper for 8-inch round sheet metal duct systems in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation is performed by licensed sheet metal contractors or HVAC technicians following SMACNA duct construction standards. Power down the air handling unit and confirm zero airflow before inserting or repositioning the damper. Secure the damper in the duct sleeve according to manufacturer fitment requirements and verify the blade operates freely through its full range before restoring system operation. Follow local mechanical codes for damper placement in branch takeoffs and zoning applications.
