Complete Guide to Cutting Cable Tray Bends on-site

Cable tray bends can be created efficiently on-site using proper cutting tools, safety measures, and step-by-step bending techniques for horizontal, vertical, tee, cross, and offset configurations.

Tools Required

• Bolt cutter or cable cutter for wire mesh trays, which preserves protective coatings on cut edges
• Circular saw or cordless bandsaw for metal trays, ensuring precise cuts with minimal debris
• Angle grinder for flexible cutting, though it requires careful handling to avoid sparks and injury
• Measuring tape, marker/chalk, pliers, and hand gloves for accurate marking and safe handling

Safety Precautions

• Always wear Kevlar gloves, eye protection, and appropriate PPE when cutting or bending
• Protect surrounding materials from sparks and overheating during metal cutting
• Avoid using torches, as they can damage surface treatments and weaken the material

Step-by-Step Cutting and Bending Methods

1. Horizontal 90° Bend (Flat Bend)

• Mark the bend area clearly on the tray
• Use a bolt cutter (wire mesh) or saw (metal) to cut along the marked line
• Bend the tray manually or with a bending tool to achieve a flat 90° angle

2. Vertical Bend (Up/Down Bend)

• Measure the required vertical offset and mark the tray
• Cut the tray partially if needed to allow smooth bending
• Use pliers or a bending machine for metal trays to achieve the vertical angle

3. Tee (T-Junction) Bend

• Identify the intersection point and mark the tray
• Cut the tray to create the branch section
• Bend the branch to form a T-junction, ensuring alignment with the main tray

4. Cross Bend (4-Way Junction)

• Mark the four-way intersection points
• Cut the tray sections to allow the cross configuration
• Bend each section carefully to form a stable 4-way junction

5. Offset Bend (Side Shift)

• Measure the required lateral shift and mark the tray
• Make precise cuts to allow the tray to shift sideways
• Bend the tray to achieve the offset without compromising structural integrity

Additional Tips

• Always deburr cut edges to prevent injuries and maintain protective coatings
• For wire mesh trays, rubber caps can be used to protect cut ends
• Apply these cutting guidelines in 3D plant software for planning and optimal installation
• Use cordless saws with chip collectors for clean, low-noise cuts in confined spaces By following these methods, installers can achieve professional, safe, and efficient cable tray bends on-site without relying on expensive pre-fabricated fittings.
