Southwark Metal MR_26IN Duct Mounting Rail 26 Inches

Product Description

The SOUTHWARK METAL MR_26IN is a snap-on mounting rail designed for securing sheet metal ductwork in HVAC installations. Fabricated from hot-dip galvanized steel, this rail delivers corrosion resistance suited for both conditioned and unconditioned spaces where moisture exposure is a concern. At 26 inches in length, it provides a stable, rigid attachment point along the duct body. HVAC sheet metal mechanics and duct installers use this rail to support and position rectangular sheet metal duct runs during installation, keeping sections aligned and reducing stress on duct joints over the service life of the system.

This mounting rail is used in residential and light commercial HVAC duct systems where sheet metal duct is the primary distribution medium. The snap-on design allows it to attach directly to standard sheet metal duct without additional fasteners at the point of engagement, speeding up installation on duct runs where multiple support points are required. It is particularly well suited for suspended duct systems in mechanical rooms, basements, crawlspaces, and plenum spaces where consistent support spacing is required per ACCA and SMACNA guidelines.

Key Features

• Hot-dip galvanized steel construction provides durable corrosion resistance
• Snap-on attachment simplifies installation on sheet metal duct without additional fasteners at the rail interface
• 26-inch length accommodates standard rectangular duct widths
• Manufactured to ACCA and SMACNA applicable standards for duct support and installation
• Rigid rail profile maintains duct alignment along horizontal and vertical runs

Compatibility

Designed for use with sheet metal duct systems. Specific compatible duct sizes and configurations should be verified against SMACNA duct construction standards and the installer's duct layout drawings.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal mechanics working to SMACNA and ACCA duct installation standards. Support spacing should comply with SMACNA HVAC Duct Construction Standards for the applicable duct size and orientation. Ensure the duct section is de-pressurized and the air handling unit is powered down before making any modifications to an existing duct run. Do not use the mounting rail as a structural hanger point beyond its intended duct-support function.
