The cable tray does not have a vertical tee

If your cable tray system lacks a vertical tee, you can either use manufacturer-supplied vertical tee fittings, create a custom fitting, or simulate the connection using elbows and risers.

Manufacturer Fittings

Vertical tees are available from several cable tray manufacturers and are designed to integrate with standard NEMA-class cable trays. For example, Power Utility Products Co offers vertical tees compatible with Class 1, 2, and 3 cable trays, with appropriate side rail flanges and splice plates for secure connections . Similarly, I-BEAM ladder tray systems provide vertical tee-up fittings for reliable vertical branching . These fittings allow a main horizontal tray to branch vertically without compromising structural integrity or cable management.

Custom or Software-Based Solutions

If a pre-made vertical tee is not available in your design software (e.g., Revit), you can create a custom family or simulate the vertical branch using a combination of horizontal runs and elbows. One approach is to create a horizontal run, add a vertical elbow to change elevation, and then continue with another horizontal run at the new level. This method effectively mimics a vertical tee and allows proper cable routing . Multiport parts can also be used as an alternative to a tee in software modeling.

Practical Considerations

When implementing a vertical branch, ensure that the bend radius and spacing comply with cable specifications to prevent damage. Use appropriate supports and splice plates to maintain structural stability. If using a custom or simulated solution, verify that the installation allows smooth cable transitions and meets safety and code requirements . By combining manufacturer fittings or custom modeling techniques, you can achieve a functional vertical tee connection even if your current cable tray system does not include one.
