Bends are installed on both sides of the cable tray

Bends on both sides of a cable tray should be installed in pairs, properly secured, and aligned to maintain structural integrity and cable protection.

Bends are essential components of a cable tray system, allowing the tray to change direction horizontally or vertically. Horizontal bends adjust the tray along the same plane (e.g., 30°, 45°, 90°), while vertical bends, or risers, allow the tray to move between elevations . Installing bends on both sides of a tray is common when creating a transition or routing cables around obstacles, ensuring smooth cable flow and preventing sharp angles that could damage cables .

• Install in Pairs: Bends should be installed symmetrically on both sides of the tray to maintain balance and structural stability . This is particularly important for risers or when fabricating custom angles.
• Secure Fastening: Use appropriate splice plates, bolts, and nuts to secure bends to the tray. For example, EzyTrays recommend using SBH and CNH splice nuts and bolts, with smooth heads facing inward to avoid cable damage .
• Support and Alignment: Ensure that each bend is supported at least twice along its length using brackets, hangers, or hold-down units. Proper alignment prevents sagging and maintains the minimum bend radius for cables .
• Minimum Bend Radius: Respect the minimum bend radius for the cables exiting the tray to avoid twisting, crushing, or sheath damage . This is critical for maintaining cable performance and longevity.
• Grounding and Bonding: For metal trays, ensure that bends and supporting structures are connected to the protective earth (PE) or protective neutral (PEN) conductor at multiple points to maintain equipotential bonding .

• Material Selection: Choose bends made from the same material and finish as the main tray to ensure compatibility and corrosion resistance .
• Custom Fabrication: For complex routing, riser links or TX brackets can be used to fabricate tees, crosses, or angled bends, always installed in pairs for stability .
• Cable Protection: Ensure bends do not create sharp edges or pinch points; covers or radius plates can provide additional protection for sensitive cables .

By following these guidelines, bends installed on both sides of a cable tray will provide safe, reliable, and structurally sound cable routing, minimizing the risk of cable damage and ensuring compliance with industry standards .
