Southwark Metal ATHEWD_10IN Duct Takeoff with Damper 10 in

Product Description

The SOUTHWARK METAL ATHEWD_10IN is a 10-inch diameter Air-Tite, high-efficiency sheet metal duct takeoff with an integrated damper, built for residential and light commercial HVAC ductwork systems. Constructed from hot-dip galvanized steel, this fitting provides a durable, corrosion-resistant connection between a main trunk duct and a branch run. The built-in damper allows airflow adjustment at the takeoff point, giving installers precise control over zone balancing without adding a separate component. HVAC technicians and sheet metal contractors are the primary installers for this type of fitting.

This duct takeoff is suited for forced-air heating and cooling systems where branch duct connections require both a secure fitting and adjustable airflow control. It is appropriate for new construction and retrofit applications in residential and light commercial settings. The Air-Tite designation indicates a design focused on minimizing air leakage at the connection point, which supports system efficiency and helps meet ACCA and SMACNA standards for duct construction and installation.

Key Features

• 10-inch diameter opening for standard branch duct connections
• Integrated damper for on-site airflow balancing without additional hardware
• Hot-dip galvanized steel construction for corrosion resistance and long service life
• Air-Tite, high-efficiency design minimizes air leakage at the takeoff joint
• Meets ACCA and SMACNA applicable standards for duct fabrication and installation

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 10-inch diameter branch connections in residential and light commercial forced-air duct systems built to ACCA and SMACNA standards.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal contractors. Shut down the air handling unit and confirm the system is de-energized before cutting into an existing trunk duct or fitting the takeoff on new ductwork. Secure the fitting and seal all joints with listed duct sealant or mastic per SMACNA guidelines to maintain Air-Tite performance. Set the damper position during system commissioning and airflow balancing.
