Southwark Metal TD_12X8X60 Sheet Metal Trunk Duct

Product Description

The SOUTHWARK METAL TD_12X8X60 is a hot-dip galvanized steel sheet metal trunk duct measuring 12 inches by 8 inches by 60 inches. It is designed for supply and return air distribution in residential and light commercial forced-air HVAC systems. The duct section features a button snap-lock seam with S-cleat and drive connection ends for fast, secure field assembly. Cross-breaking on the flat panels adds rigidity and reduces sheet metal flex noise under airflow. Licensed HVAC technicians and sheet metal contractors install this duct as part of a trunk-and-branch distribution layout.

This trunk duct section is suited for rectangular supply or return trunk runs in forced-air heating and cooling systems. The 60-inch length provides a full 5-foot run per section, making it practical for straight trunk extensions in residential attics, basements, crawlspaces, and mechanical rooms. The drive-and-cleat connection system allows straight-line assembly without additional fittings at each joint. It meets ACCA and SMACNA standards for sheet metal duct fabrication and installation.

Key Features

• Hot-dip galvanized steel construction for corrosion resistance in conditioned and unconditioned spaces
• Button snap-lock seam provides a secure longitudinal closure without additional fasteners
• S-cleat and drive connection ends allow fast field assembly and straight duct runs
• Cross-broken panels increase rigidity and reduce drumming under system static pressure
• Complies with ACCA and SMACNA fabrication and installation standards
• Full 60-inch section length minimizes the number of joints in long trunk runs

Compatibility

Designed as an OEM-style replacement and new-installation trunk duct section for rectangular forced-air HVAC duct systems built to SMACNA and ACCA standards.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal contractor in accordance with SMACNA duct construction standards and local mechanical codes. Power down the air handling unit and close the system before cutting into or extending an existing trunk. Secure all drive-and-cleat connections with sheet metal screws and seal longitudinal and transverse joints with UL 181-listed mastic or foil tape as required by local code. Support the duct at intervals specified by SMACNA to prevent sagging and vibration transmission.
