The side diameter or thickness of a cable tray, particularly ladder-type trays, is a critical parameter that affects structural strength, cable support, and installation, and it can be modified in design specifications or software with careful consideration.

Understanding Side Rail Thickness

The side rail thickness (or "side diameter") of a cable tray determines its load-bearing capacity and rigidity. Standard ladder cable trays often have side rails ranging from 1" (25 mm) for default models to thinner options like 12 SWG (2. 54 mm) C-shaped flange-out types for lighter applications.

Changing the side rail thickness affects the tray's ability to support cables, especially over long spans, and must comply with manufacturer specifications and applicable standards such as NEC, NEMA, or IEC.

Modifying Side Rail Thickness in Design

Software Limitations: In some design software (e.g., Revit), the thickness parameter is available for fittings but not for straight runs. Users often need to adjust the straight sections manually or use annotations to indicate the desired material thickness. Alternative Approaches: Use custom families or parametric models to define the side rail thickness for straight runs.

Apply detail notes or keynotes in drawings to specify the material thickness for fabrication or client presentations. Adjust the height or depth of the tray if the software allows, but note that this does not change the actual material thickness.

Practical Considerations

Cable Support: Thinner side rails may reduce structural strength, so rung spacing and tray width must be considered. For small-diameter control or instrumentation cables, closer rung spacing (6–12 inches) is recommended to prevent drooping. Material Selection: Aluminum and steel are common materials.

Aluminum offers corrosion resistance, while steel provides higher strength. The chosen thickness should balance weight, cost, and load requirements. Installation Notes: Ensure that the modified side rail thickness does not violate the minimum bending radius of cables or compromise NEC fill compliance.

Summary

Changing the side rail thickness of a cable tray is feasible but requires attention to structural integrity, cable support, and design software limitations. For straight runs in software like Revit, direct modification may not be available, so using custom families or detailed annotations is the recommended approach. Always verify that the modified thickness meets load, span, and code requirements for the intended application.
