Cable trays run on top of cabinet

Cable trays can be securely mounted on top of cabinets using specialized support brackets or elevated hardware to ensure proper cable management and safety. Methods for Mounting Cable Trays1. Direct Mounting with FASP Supports Wire mesh cable trays, such as Cablofil trays, can be bolted directly to the top of a cabinet using an FASP support.

This method provides a stable base for the tray and is suitable when the tray does not need to be elevated above the cabinet surface. 2. Elevated Mounting If the cable tray needs to be raised above the cabinet—for example, to allow airflow or accommodate other equipment—UFS support brackets or FASP supports elevated with threaded rods can be used.

This allows precise height adjustment and maintains a secure installation. 3. Ladder Tray Installation For ladder-style cable trays, such as Hubbell's NEXTFRAME® Ladder Tray, the tray can be mounted on cabinet tops using J-bolt kits and by drilling holes as required.

Ladder trays provide mechanical support for long cable runs, allow smooth bends, and help with strain relief.

Best Practices

Load Considerations: Ensure the tray's load capacity matches the weight of the cables and any additional equipment. The load class of the tray defines its safe span and carrying capability. Cable Management: Use proper banding and alignment to prevent cable sagging and maintain serviceability.

Bundles should be balanced and aligned vertically when stacked. Safety: Cable trays are designed to support cables, not people. Avoid using trays as walkways or for supporting personnel.

Modular Configuration: Choose modular systems that can be easily adjusted for new or existing cable routing, allowing flexibility in data center or network room layouts.

Summary

Running cable trays on top of cabinets is a common practice in data centers and network installations.

Using FASP or UF

S supports for wire mesh trays, or J-bolt kits for ladder trays, ensures secure mounting. Always consider load capacity, proper cable alignment, and safety guidelines to maintain a reliable and serviceable cable management system.
