Yes, wire mesh cable trays can be bent on-site to create horizontal, vertical, tee, cross, and offset bends without the need for expensive fittings.

Flexibility and Advantages

Wire mesh cable trays are designed for flexibility and easy on-site modification, unlike rigid or perforated trays. Bending them allows installers to navigate corners, structural obstacles, and complex layouts while maintaining a continuous tray system. This approach reduces the number of joints, improves cable protection, and provides a clean, professional appearance for installations .

Common Types of Bends

• Horizontal 90° Bend: Changes the tray direction within the same horizontal plane, ideal for routing around walls or machinery .
• Vertical Bend (Up/Down): Adjusts the tray elevation to go over or under obstacles .
• Tee (T-Junction) and Cross (4-Way Junction): Allows branching of cable routes in multiple directions .
• Offset Bend (Side Shift): Shifts the tray laterally to align with architectural constraints .

Tools and Techniques

Bending wire mesh trays typically requires basic tools such as bolt cutters, pliers, measuring tape, and markers. The process involves marking the bend area, cutting or loosening specific mesh threads if necessary, and carefully bending the tray to the desired angle while maintaining a smooth radius to protect cables . Some systems, like Cablobend, allow adjustable bends without cutting, further simplifying installation and reducing labor time .

Installation Considerations

• Maintain proper bend radius to prevent cable damage, especially for Ethernet or fiber optic cables .
• Reinforce bends if needed to preserve tray strength.
• Verify grounding and bonding after modifications.
• Avoid overfilling trays at corners to ensure proper cable management . By following these guidelines, wire mesh cable trays can be bent efficiently and safely, providing a versatile solution for complex electrical installations.
