Southwark Metal TD_22X14X48 Trunk Duct 22x14x48

Product Description

The SOUTHWARK METAL TD_22X14X48 is a hot-dip galvanized steel sheet metal trunk duct section measuring 22 inches by 14 inches by 48 inches in length. It ships with button snaplock seams, S-cleat, and drive connection hardware already integrated into the profile. The cross-broken panel design adds stiffening strength to reduce flex and noise transmission at higher static pressures. Licensed HVAC sheet metal mechanics install this component as a primary supply or return trunk run in forced-air duct systems. It meets ACCA and SMACNA fabrication standards.

This trunk duct section is used in residential and light commercial forced-air HVAC systems where a rectangular main trunk is required. The 22-inch by 14-inch cross-section suits medium-to-large air-handling applications. The 48-inch section length is a standard field module, making it straightforward to stage and connect in sequence along a trunk line. Installers connect sections using the included S-cleat and drive connections, eliminating the need for separate connector hardware at the job site.

Key Features

• Hot-dip galvanized steel construction resists corrosion in attic, crawlspace, and mechanical room environments
• Button snaplock seam with S-cleat and drive connection — hardware is built into the section, no separate fittings needed
• Cross-broken panels add structural rigidity and reduce oil-canning and vibration transmission
• Meets ACCA and SMACNA applicable standards for sheet metal duct fabrication
• 48-inch section length aligns with standard trunk layout increments for efficient field installation

Compatibility

Designed as an OEM-style rectangular trunk duct section for residential and light commercial forced-air HVAC duct systems requiring a 22-inch by 14-inch cross-section trunk configuration.

Installation Notes

Sheet metal trunk duct installation is performed by licensed HVAC technicians or journeyman sheet metal workers following SMACNA and ACCA duct construction guidelines. Power down and lock out the air handler or furnace before connecting or modifying any duct section. Sections are joined using the integrated S-cleat and drive connections; seal all seams with UL 181-rated duct sealant or mastic per local mechanical code requirements. Support hangers should be spaced per SMACNA hanger and support tables for the duct size and weight involved.
