Obo Mesh Cable Tray Patent

OBO Bettermann's GR-Magic® mesh cable tray system features patented innovations for rapid, tool-free installation and field-adaptable components that maintain electrical compliance. GR-Magic® Connection SystemOBO Bettermann's GR-Magic® mesh cable tray incorporates a patented connection system that allows trays to be connected in seconds without additional tools or connectors, even for straight or complex routing configurations. This system eliminates the need to store separate connection parts, reducing costs and installation time.

Load tests confirm that the GR-Magic® system maintains stability and load-bearing capacity comparable to traditional screw connections, while also meeting electrical standards such as VDE 0639 and IEC/EN 61537. The system can also be fastened to brackets without screws, enhancing flexibility in installation.

Field-

Adaptable Components and ComplianceOBO has patented components that allow bends and elevation offsets in wire mesh cable trays while preserving the cross-sectional area and equipment-ground conductor (EGC) compliance. These components can be modified and installed either by the manufacturer or directly in the field by technicians, ensuring that electrical conductivity and structural integrity are maintained. This adaptability is particularly useful for low-voltage, telecommunication, and fiber-optic cable installations, where precise routing and compliance with standards like UL, CSA, and NEC are critical.

Bonding Clips and Electrical Connectivity

Another patented innovation involves bonding clips that electronically bond adjacent wire mesh trays. These clips penetrate the protective coating of the tray wires to ensure conductive contact while maintaining the tray's cross-sectional area. This design supports both mechanical stability and electrical grounding, which is essential for safety and compliance in professional electrical installations.

Advantages of OBO Patented Systems

Rapid installation: Tool-free and connector-free assembly for straight and complex tray layouts. Field adaptability: Components can be modified on-site to accommodate bends and elevation changes without compromising EGC compliance. Electrical and mechanical compliance: Meets VDE, IEC/EN, UL, and NEC standards.

Fire and load testing: GR-Magic® trays have been tested for fire resistance and load-bearing capacity, supporting up to 15 kg/m with 1. 5 m support spacing.
