Southwark Metal ATD_6IN Duct Takeoff Damper 6 Inch

Product Description

The SOUTHWARK METAL ATD_6IN is a 6-inch diameter Air-Tite sheet metal duct takeoff with an integrated damper, fabricated from hot dip galvanized steel. Duct takeoffs connect branch runs to main trunk ducts in forced-air HVAC distribution systems, and this fitting is designed to provide a tight, controlled connection point. The built-in damper allows airflow balancing within the branch run without requiring a separate balancing component. Licensed HVAC technicians and sheet metal mechanics are the primary installers of this fitting in residential and light commercial duct systems.

This takeoff is suited for use in forced-air heating and cooling systems where branch ducts are run from a main rectangular or round trunk. The Air-Tite designation indicates a construction standard aimed at reducing air leakage at the takeoff connection, which supports system efficiency and helps meet duct leakage requirements under energy codes such as ACCA Manual D and SMACNA standards. It is appropriate for new construction and retrofit duct work where a 6-inch branch is required.

Key Features

• 6-inch diameter opening for standard branch duct connections
• Hot dip galvanized steel construction for corrosion resistance in HVAC air distribution environments
• Integrated damper for in-line airflow balancing without additional hardware
• Air-Tite construction to minimize air leakage at the takeoff joint
• Meets ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style sheet metal fitting for use in residential and light commercial forced-air duct systems requiring a 6-inch diameter branch takeoff connection.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal mechanic in accordance with SMACNA duct construction standards and local mechanical codes. Shut down the air handling unit and confirm the system is de-energized before cutting into any existing duct section. Secure the takeoff with sheet metal screws and seal all joints with listed duct sealant or mastic per applicable energy code requirements. Set the integrated damper position during system commissioning and balance airflow before finalizing the installation.
