Southwark Metal TD_12X8X48 Trunk Duct 12x8x48 in

Product Description

The SOUTHWARK METAL TD_12X8X48 is a rectangular sheet metal trunk duct section fabricated from hot dip galvanized steel. It measures 12 inches by 8 inches in cross section and 48 inches in length. The section uses a button snap-lock seam with S-cleat and drive connection ends, making field assembly straightforward without specialized tooling. Cross breaking is applied to the flat panels to add rigidity and reduce sheet metal drumming under airflow. This duct section is installed by licensed HVAC technicians and sheet metal contractors as part of forced-air distribution systems in residential and light commercial applications.

This trunk duct section is suited for main supply or return trunk runs in forced-air HVAC systems. The 12 x 8 inch rectangular profile fits standard framing cavities and furring spaces commonly found in residential construction. The drive and S-cleat end connections allow back-to-back joining of multiple sections to achieve the required run length. Fabrication to ACCA and SMACNA standards ensures the section meets industry duct construction requirements for leakage and structural integrity.

Key Features

• Hot dip galvanized steel construction for corrosion resistance in conditioned and unconditioned spaces
• Button snap-lock longitudinal seam for secure, consistent closure along the 48-inch length
• S-cleat and drive connection ends for fast, tool-minimal joining to adjacent duct sections or fittings
• Cross-broken flat panels add stiffness and reduce vibration and drumming under static pressure
• Fabricated to ACCA and SMACNA applicable standards for duct construction

Compatibility

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

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. Shut down and lock out the air handling unit before connecting or modifying any duct section. Drive and S-cleat connections should be fully seated and secured before sealing joints with UL 181-listed mastic or metal foil tape as required by local code. Duct hangers and supports should be spaced per SMACNA guidelines to prevent sagging along the run.
