Southwark Metal TD_14X10X48 Sheet Metal Trunk Duct 14x10x48

Product Description

The SOUTHWARK METAL TD_14X10X48 is a galvanized steel sheet metal trunk duct section measuring 14 inches wide by 10 inches tall by 48 inches long. Fabricated from hot dip galvanized steel, it provides durable, corrosion-resistant performance in forced-air distribution systems. The section ships with a button snap-lock seam and connects to adjacent sections using an S-cleat and drive connection. Cross breaking is applied to the flat panels to reduce drumming and improve rigidity. HVAC sheet metal mechanics install this trunk duct as part of main supply or return air distribution runs in residential and light commercial systems.

This trunk duct section is suited for low-pressure forced-air supply and return trunk runs in residential new construction, retrofit, and light commercial HVAC applications. The 14 x 10 inch cross-section accommodates standard rectangular duct layouts and fits within typical joist-bay and drop-ceiling plenum spaces. It is designed for systems where trunk and branch duct layout follows ACCA Manual D sizing principles. Sheet metal fabricators and HVAC installation contractors use this section alongside fittings, transitions, and takeoffs to complete main duct runs.

Key Features

• Hot dip galvanized steel construction for corrosion resistance in conditioned and unconditioned spaces
• Button snap-lock seam for fast, secure longitudinal closure without additional fasteners
• S-cleat and drive connection ends for standard field assembly to adjacent duct sections and fittings
• Cross-broken flat panels to reduce oil-canning noise and add panel rigidity
• Meets ACCA and SMACNA applicable standards for low-pressure duct fabrication

Compatibility

Designed as an OEM-style replacement and new-construction trunk duct section for standard rectangular low-pressure forced-air HVAC duct systems using S-cleat and drive connections.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal mechanic in accordance with SMACNA duct construction standards and local mechanical codes. Power down the air handling system before connecting or disconnecting any duct section. Secure S-cleat and drive connections fully before applying duct sealant or tape per local code requirements. Support hangers should be spaced per SMACNA guidelines to prevent sagging along the duct run.
