How to Select the Right Cable Cleat

Choosing the correct cable cleat to protect your project will assure optimal performance, reliability, and quality. Panduit has solutions to suit a variety of environmental conditions, industrial applications, and short circuit fault current requirements.

Having the right cable cleat provides restraint and protection in the event of a short circuit fault. Panduit has developed the Cleat kAlculator™ to help engineers, designers, and installers determine the correct cable cleat for their application.

To simplify this selection decision, three easy steps allow users to:
  1. Select a cable layout
  2. Input cable outer diameter
  3. Input peak short circuit current

The Cleat kAlculator™ is available for download in the Apple Store
or Google Play.

When Selecting Cable Cleats, Consider a Variety of Factors

Cable Layout: How the cables are arranged and secured will determine which cable cleat fits them best.

Cable Outer Diameter: The diameter of the cable determines what the correct size of cleat is and is also required for calculating the short circuit forces the cleat could face.

Environment Performance: The cable cleat should have the material and specification features needed for it to withstand the elements it will face. Examples include flame rating, extreme temperatures, or chemical and corrosion resistance.

Using this data, force between conductors during short circuit event can be calculated and the correct cleats at appropriate spacing can be determined. Cleat spacing is always a function of the peak kA, distance between the centers of neighboring conductors, and the rated strength of a cleat.

NEC 392.20(C) and The Cable Tray Institute provide guidelines for securing cable on horizontal and vertical runs, but cable cleat spacing is determined by the calculated forces during a short circuit fault. For horizontal, vertical and radius sections of the cable run, additional cable restraints beyond the minimum cable cleat requirements may be required for proper cable management. 

Panduit’s extensive line of cable cleat solutions provides various options to fit the needs of the project and provide job productivity, reliability, and safety. Panduit recommends the following solutions: stainless steel locking strap cleat, stainless steel buckle strap cleat, stainless steel trefoil cleat, and aluminum and polymer cleats. These cable cleats are designed to perform in a wide range of harsh environments, reduce material cost, and reduce installation time.

Lab tests performed on Panduit cable cleats verify strength of cleats and provide a baseline rating, in addition to being validated at a third-party test facility to ensure they perform to specifications when needed.

The simple and intuitive design leads to increased productivity, and they are compatible with a variety of ladder racks and cables.
