How to install horizontal and vertical bends in cable trays

Horizontal bends redirect the tray along a flat plane, while vertical bends allow the tray to change elevation; both can be made on-site using cutting and bending techniques with proper tools and reinforcement.Horizontal BendsPurpose: Horizontal bends change the direction of the cable tray along a horizontal plane, typically to navigate corners or follow room layouts . Typical Angles: 30° to 90°, depending on space and cable routing requirements . Process:Mark the Bend Points: Measure and mark the tray where the bend is required. Tools like a cable tray offset calculator can help determine precise points and sloped section lengths .Cut the Mesh: For wire mesh trays, cut the mesh at precise points to allow smooth bending. Use a bolt cutter or angular blade cutter for clean cuts .Bend the Tray: Apply force gradually to bend the tray along the horizontal plane. Reinforce the bend points if the angle is sharp to maintain structural integrity .Check for Smoothness: Ensure the bend is smooth to prevent cable damage during installation .Vertical BendsPurpose: Vertical bends allow the tray to transition between different elevations, such as from floor to ceiling or between floors . Typical Angles: Usually 30° to 90°, depending on the required elevation change . Process:Mark the Elevation Change: Determine the start and end points of the vertical bend.Cut the Tray: Similar to horizontal bends, cut the mesh or tray at designated points to facilitate bending .Bend Upward or Downward: Gradually bend the tray along the vertical plane, ensuring a smooth transition to minimize stress on cables .Reinforce and Inspect: Reinforce the bend if necessary and check for sharp edges that could damage cables .Tools and TipsBolt Cutters or Angular Blade Cutters: Essential for cutting wire mesh trays cleanly without damaging protective coatings .Bending Machines or Metal Bars: For steel trays, a bending machine or a sturdy metal bar can help achieve precise bends .Reinforcement: Add support at sharp bends to maintain tray strength and prevent sagging .Safety: Always wear gloves and eye protection when cutting or bending trays. By following these steps, you can create both horizontal and vertical bends on-site, ensuring a safe, smooth, and structurally sound cable tray installation.
