Southwark Metal TD_18X8X60 Sheet Metal Trunk Duct 18x8x60

Product Description

The SOUTHWARK METAL TD_18X8X60 is a hot-dip galvanized steel sheet metal trunk duct section measuring 18 inches by 8 inches by 60 inches. It is designed for use in forced-air HVAC distribution systems where rectangular trunk duct runs carry conditioned air from the air handler or furnace to branch takeoffs. The duct features a button snap-lock seam with S-cleat and drive connection ends, allowing fast field assembly without separate fasteners. Cross-breaking on the flat panels adds rigidity and reduces oil-canning under system pressure. Licensed HVAC mechanics and sheet metal contractors are the primary installers.

This trunk duct section fits residential and light commercial forced-air installations where a rectangular main trunk is required. It is appropriate for supply air systems in new construction and retrofit applications. The 18-inch by 8-inch cross-section accommodates trunk runs requiring that profile, and the 60-inch length matches standard rough-in spacing. The hot-dip galvanized finish provides corrosion resistance suitable for attic, crawlspace, basement, and conditioned-space installations. This section is fabricated to ACCA and SMACNA standards, making it compatible with systems designed under those guidelines.

Key Features

• Hot-dip galvanized steel construction for corrosion resistance in varied install environments
• Button snap-lock longitudinal seam for secure, airtight assembly
• S-cleat and drive connection ends for fast, tool-minimal field joining
• Cross-broken flat panels increase rigidity and reduce panel flex under airflow pressure
• Fabricated to ACCA and SMACNA applicable standards
• 18 x 8 inch cross-section in a 60-inch length for standard trunk layout spacing

Compatibility

Designed as an OEM-style sheet metal trunk duct section for rectangular forced-air supply systems built to ACCA and SMACNA standards. Compatible with standard S-cleat and drive-connection fittings of matching 18-inch by 8-inch profile.

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 and lock out the air handling unit before connecting or modifying any duct section. Secure all joints with the appropriate S-cleat and drive fasteners and seal longitudinal seams and end connections with listed duct sealant or mastic per local code requirements. Support the trunk duct at intervals specified by SMACNA hanger and support guidelines to prevent sagging and joint separation.
