Southwark Metal TD_22X8X48 Sheet Metal Trunk Duct 22x8x48

Product Description

The SOUTHWARK METAL TD_22X8X48 is a hot dip galvanized steel sheet metal trunk duct measuring 22 inches by 8 inches by 48 inches. It is designed for use in forced-air HVAC distribution systems where a rigid rectangular main trunk line is required. The duct section features a button snap-lock seam with S-cleat and drive connection ends, allowing for fast, secure field assembly. Cross-breaking adds rigidity to the panel faces, reducing noise and flex under system pressure. Licensed HVAC sheet metal contractors and mechanical installers work with this component during new construction and retrofit duct installations.

This trunk duct section is suited for residential and light commercial forced-air systems where a rectangular main supply or return trunk is routed through framed ceilings, crawlspaces, basements, or mechanical rooms. The 22 x 8 inch cross-section accommodates mid-range airflow capacities typical of main trunk runs in residential split systems and packaged units. The 48-inch length is a standard field-work size that fits most joist bay spacings and simplifies layout on long straight runs.

Key Features

• Hot dip galvanized steel construction for corrosion resistance in humid or unconditioned spaces
• Button snap-lock seam for quick, secure longitudinal closure without additional fasteners
• S-cleat and drive connection ends allow inline splicing and branch takeoff connections
• Cross-broken panel faces add structural rigidity and reduce drumming under airflow pressure
• Meets ACCA and SMACNA applicable standards for sheet metal duct fabrication
• Standard 48-inch length simplifies layout and reduces field cutting on straight trunk runs

Compatibility

Designed as an OEM-style rectangular trunk duct section compatible with standard S-cleat and drive connection duct systems used in residential and light commercial forced-air HVAC installations.

Installation Notes

Installation should be performed by a licensed HVAC or sheet metal contractor in accordance with SMACNA duct construction standards and local mechanical codes. Shut down and lock out the air handling system before connecting or modifying any duct section. Use appropriate sheet metal snips, drive cleats, and S-cleat stock to complete end connections; secure all seams and joints with approved duct sealant or listed duct tape per local code requirements. Support spacing should follow SMACNA hanger and support guidelines for rectangular ductwork.
