How to adjust a mesh cable tray to a 90-degree angle

Mesh cable trays can be installed at 90-degree angles using proper bending techniques or pre-fabricated bend kits, ensuring cable protection and compliance with standards.Creating 90-Degree BendsMesh cable trays are designed for flexibility, allowing installers to create bends on-site. To form a 90-degree angle, technicians typically cut the bottom wires of the tray and bend the tray up or down to the required angle. All cut edges should be covered with edge protection strips or rubber sleeving to prevent damage to cable insulation during installation . Alternatively, pre-fabricated 90-degree bend kits are available, which simplify installation and eliminate the need for precise tray alignment .Using AccessoriesBend kits and tees are designed to fit any size tray and provide structural support while maintaining the tray's open mesh design. These accessories allow for rapid installation and flexibility in routing cables through complex configurations . When using these kits, ensure that all hardware is properly secured and that the tray sections are bonded together for grounding purposes.Compliance and SafetyAccording to NEC Article 392, cable trays must be properly supported, grounded, and capable of safely carrying the intended cables. The open design of mesh trays allows cables to be laid from the top or side, but cables must be Type TC (Tray Rated) or metal-armored (Type MC) to withstand exposure . Grounding clips or jumpers should bond each tray section to the facility's main grounding busbar to maintain electrical safety .Best PracticesMaintain the minimum bend radius for cables to prevent stress or damage.Use edge protection at all exit points and bends.Ensure proper support spacing to prevent sagging, especially at bends.Verify that all bends and tees comply with local electrical codes and manufacturer recommendations . By following these guidelines, mesh cable trays can be safely and efficiently installed at 90-degree angles while protecting cables and ensuring compliance with electrical standards.
