Trough Cable Tray
Solid Bottom Cable Tray Systems for Enclosed and Protected Cable Routing
IEC 61537 Compliant
Available in Multiple Load Classes and Material Options
Compatible with Complete Cable Tray Support and Accessory Systems
Solid bottom cable tray systems are designed for applications requiring enhanced cable protection, environmental isolation, and organized cable routing.
The fully enclosed structure provides protection against dust, debris, moisture, and accidental mechanical damage while offering improved electromagnetic shielding for sensitive control, instrumentation, and communication cables.
The system is available in multiple dimensions, material grades, and enclosure configurations, and can be supplied together with compatible fittings, support systems, and accessories as a complete cable management solution.
