Cable tray angle adjusters allow precise horizontal or corner adjustments in cable tray systems, ensuring proper alignment and secure support for electrical cables.

Tools and Preparation

Before installation, gather the necessary tools: a wrench, drill, and metal cutting tools if field modifications are required . Ensure the cable tray and angle adjuster components are clean, free of damage, and compatible in size. Determine the desired angle for the tray adjustment and mark the cutting or attachment points on the tray .

Installation Steps

1. Position the Adjuster: Insert the adjustable angle piece (e.g., SRS or flexible horizontal splice plate) inside the cable tray at the intended junction .
2. Field Cutting (if required): Measure and mark the cable tray where cuts are needed to fit the adjuster. Remove any rungs that interfere with the cut, and carefully cut the tray using a metal cutting tool .
3. Attach Hardware: Secure the angle adjuster using the included screws or bolts. Ensure all fasteners are tightened evenly to maintain structural integrity .
4. Support Spacing: Install supports within 24 inches (600 mm) on both sides of the adjuster to comply with NEMA VE2 standards and prevent sagging .
5. Alignment Check: Verify that the tray sections are aligned correctly and that the angle adjuster allows the intended directional change without stressing the tray or cables .

Safety and Compliance

• Only qualified personnel familiar with electrical installation practices should perform the installation .
• Cable trays are mechanical support systems, not walkways or lifting devices .
• Follow local electrical codes (e.g., Canadian Electrical Code, BS EN 61537) and manufacturer guidelines to ensure safe and compliant installation .
• Avoid over-tightening fasteners, which can deform the tray or adjuster, and ensure proper grounding if required by the system design .

Maintenance Tips

• Inspect the angle adjuster and tray periodically for loose hardware or corrosion.
• Ensure that cable loads do not exceed the tray's rated capacity.
• Keep documentation of the installation layout for future modifications or troubleshooting . By following these steps, a cable tray angle adjuster can be installed securely, providing flexibility in routing while maintaining compliance with safety and structural standards.
