Southwark Metal 6s12026 S Cleat 120 in 26 Gauge Galvanized

Product Description

The SOUTHWARK METAL 6s12026 is a 120-inch galvanized steel S cleat designed for joining and sealing sections of rectangular sheet metal ductwork. Formed to a standard S-profile, it slides over mating duct edges to create a secure mechanical connection between duct sections. Fabricated from 26-gauge galvanized steel meeting ASTM A-653 CS Type B, it delivers reliable corrosion resistance in both supply and return air applications. HVAC sheet metal mechanics and duct fabricators use this cleat as a primary longitudinal joint fastener during duct assembly and installation.

This S cleat is suited for residential and light commercial HVAC duct systems where rectangular galvanized ductwork is assembled on the job site or in a sheet metal shop. At 120 inches in length and 3/4 inch in width, it provides a full 10-foot run per piece, reducing the number of joints needed on long duct runs. It is appropriate for use in forced-air heating, cooling, and ventilation systems that require code-compliant duct connections.

Key Features

• Standard S-cleat profile for joining rectangular galvanized duct sections
• 26-gauge galvanized steel construction for strength and corrosion resistance
• Meets ASTM A-653 CS Type B specification for galvanized sheet steel
• 120-inch length provides a full 10-foot run per piece
• 3/4-inch width fits standard S-cleat duct edge folds

Compatibility

Designed as an OEM-style replacement and standard shop component for rectangular galvanized sheet metal ductwork systems requiring S-cleat longitudinal connections.

Installation Notes

Installation is typically performed by licensed sheet metal mechanics or HVAC technicians following SMACNA duct construction standards. Power down the air handling system before working on connected ductwork. The cleat is slid over pre-folded duct edges and crimped or driven into place using standard hand seamers or a cleat driver. Follow local mechanical codes for required joint reinforcement and sealant application on pressure-class duct systems.
