Southwark Metal ATSD_5IN Duct Takeoff 5 Inch Air-tite

Product Description

The SOUTHWARK METAL ATSD_5IN is a 5-inch diameter Air-Tite sheet metal duct takeoff designed for forced-air HVAC distribution systems. Fabricated from hot-dip galvanized steel, this takeoff includes an integrated scoop and damper assembly, allowing technicians to direct and regulate airflow at the branch point of a main trunk or plenum. The scoop improves air capture from the main duct, while the damper provides on-site balancing capability without additional hardware. Licensed HVAC mechanics and sheet metal contractors are the primary installers for this fitting.

This fitting is suited for residential and light commercial forced-air systems where branch duct takeoffs connect a main supply trunk to individual room runs. The 5-inch diameter matches common branch sizing used in bedroom and small-room supply runs. The Air-Tite designation indicates the fitting is constructed to reduce air leakage at the connection point, supporting system efficiency and comfort. Its scoop-and-damper combination makes it particularly useful in systems requiring airflow balancing across multiple zones or rooms.

Key Features

• 5-inch diameter opening matches standard branch duct sizing for residential supply runs
• Hot-dip galvanized steel construction resists corrosion in attic, crawlspace, and basement environments
• Integrated scoop improves air capture from the main supply trunk
• Built-in damper allows airflow balancing without separate hardware
• Air-Tite construction reduces leakage at the takeoff connection point
• Meets ACCA and SMACNA applicable standards for sheet metal duct fittings

Compatibility

Designed as an OEM-style replacement and new-installation fitting for residential and light commercial forced-air sheet metal duct systems requiring a 5-inch diameter branch takeoff with integrated scoop and damper.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor in accordance with SMACNA duct construction standards and local mechanical codes. Shut down and lock out the air handler or furnace before cutting into the main trunk or plenum. Secure the fitting with sheet metal screws and seal all joints with UL 181-listed mastic or tape per local code requirements. Adjust the damper after system startup to achieve proper airflow balance across all branch runs.
