Southwark Metal ATHEWD_6IN Duct Takeoff Damper 6 Inch

Product Description

The SOUTHWARK METAL ATHEWD_6IN is a sheet metal duct takeoff with an integrated damper, built for forced-air HVAC distribution systems in residential and light commercial applications. Constructed from hot-dipped galvanized steel, this Air-Tite, high-efficiency fitting is designed to minimize air leakage at branch takeoff points while providing manual damper control for balancing airflow. The 6-inch diameter inlet and 6-inch diameter outlet make it a direct-fit solution for standard round duct branch connections off a main trunk. HVAC installers and sheet metal contractors rely on this type of fitting to maintain system efficiency and meet design specifications.

This duct takeoff is suited for new construction and retrofit forced-air duct systems where branch balancing is required. The built-in damper allows technicians to throttle airflow to individual zones or runs without adding a separate balancing damper. It is appropriate for residential trunk-and-branch duct layouts as well as light commercial duct systems where ACCA and SMACNA standards govern installation and fabrication quality.

Key Features

• Integrated damper for in-line airflow balancing at the branch takeoff point
• Hot-dipped galvanized steel construction for corrosion resistance in typical HVAC environments
• Air-Tite design reduces air leakage at the takeoff connection
• High-efficiency fitting classification supports ACCA Manual D duct design requirements
• 6-inch inlet and 6-inch outlet diameter for standard round branch connections
• Meets ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 6-inch round branch duct connections in residential and light commercial forced-air HVAC systems.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Shut down and lock out the air handling unit before connecting or sealing any duct fittings. Seal all joints with mastic or UL-listed foil tape in accordance with SMACNA duct construction standards. Secure the fitting to the trunk duct using sheet metal screws at a minimum of three evenly spaced points around the collar.
