Thomas Betts AB253-TB Strut Channel Flat Plate Fitting

Product Description

The THOMAS BETTS AB253-TB is a flat plate fitting designed for use with metal framing channel and strut systems. Constructed from steel with a gold galvanized finish, this fitting serves as a structural connector in strut channel assemblies. It is used to join sections of metal framing channel, providing a flat, stable connection point in electrical, mechanical, and general construction support systems. Electricians, pipefitters, and mechanical contractors regularly use flat plate fittings when building out unistrut-style support frameworks for conduit, cable tray, piping, and equipment.

This fitting is suited for both residential and commercial applications where metal framing channel systems are used to support electrical conduit runs, plumbing lines, HVAC ductwork hangers, and similar overhead or wall-mounted assemblies. It is particularly common in industrial and commercial construction environments where strut channel grids require flat joiner plates to extend runs or reinforce connection points. Cross-referenced part numbers include Unistrut P1028 and B-Line B132.

Key Features

• Flat plate fitting profile for joining and extending metal framing channel runs
• Steel construction provides structural rigidity in support system assemblies
• Gold galvanized finish offers corrosion resistance for interior and protected exterior applications
• Compatible with standard strut channel widths used across major fitting systems
• Cross-references to Unistrut P1028 and B-Line B132 for easy replacement sourcing

Compatibility

Designed for use with joining metal framing channel and strut. Cross-references to Unistrut part number P1028 and B-Line part number B132.

Installation Notes

Installation is typically performed by electricians or ironworkers as part of a strut channel support system build-out. De-energize any nearby electrical equipment before working in the installation area. Hardware such as channel nuts and bolts appropriate for the strut profile should be used to secure the fitting. Follow applicable local building codes and NEC guidelines for support spacing and fastening requirements.
