Southwark Metal ATHEWD_8IN Sheet Metal Duct Takeoff 8 in

Product Description

The SOUTHWARK METAL ATHEWD_8IN is an Air-Tite, high efficiency sheet metal duct takeoff with an integrated damper, designed for forced-air HVAC distribution systems. Constructed from hot dip galvanized steel, this takeoff measures 8 inches in diameter and is built to meet ACCA and SMACNA standards. The included damper allows for airflow adjustment at the branch point, giving HVAC technicians precise control over zone distribution. This fitting is intended for installation by licensed HVAC mechanics working on residential or light commercial ductwork systems.

This duct takeoff is suited for use in trunk-and-branch and radial duct systems where a controlled branch connection is needed off a main trunk line. The 8-inch diameter fits common branch duct runs serving individual rooms or zones. The Air-Tite design reduces air leakage at the connection point, supporting efficient system performance in line with ACCA Manual D distribution requirements. It is appropriate for new construction and retrofit applications alike.

Key Features

• Hot dip galvanized steel construction for corrosion resistance in air distribution environments
• 8-inch diameter fits standard branch duct connections
• Integrated damper enables airflow balancing at the takeoff point
• Air-Tite design minimizes air leakage at the branch connection
• Meets ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style sheet metal duct takeoff for use in forced-air HVAC ductwork systems requiring an 8-inch diameter branch connection with damper control.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with SMACNA duct construction standards and ACCA Manual D guidelines. Shut down and de-energize the air handling system before beginning ductwork modifications. Seal all connections with approved mastic or UL 181-listed tape to maintain system airtightness. Verify damper operation and set position before returning the system to service.
