Horizontal cable trays can be bent against the wall to become vertical cable trays

Horizontal cable trays can be transitioned to vertical runs using specialized fittings such as vertical bends or helix fittings, allowing safe and space-efficient routing along walls.

Methods for Vertical Transitions

Vertical bends and helix fittings are commonly used to change the direction of cable trays from horizontal to vertical. These fittings are designed to maintain proper cable support and spacing while minimizing stress on the cables . Helix fittings, in particular, are ideal for confined areas and near walls, as they allow smooth transitions without requiring large amounts of space or complex assembly on site .

Installation Considerations

  • Support and spacing: Ensure that the vertical section is properly supported using wall brackets or other mounting elements to prevent sagging or undue stress on the cables .
  • Bend radius: Maintain the minimum bend radius recommended for the type of cable being installed to avoid damage or signal degradation .
  • Material selection: Fittings are available in aluminum, pre-galvanized steel, and stainless steel, allowing selection based on environmental conditions and load requirements .
  • Pre-assembly: Many helix fittings can be ordered pre-assembled, which reduces installation time and ensures consistent alignment .

Best Practices

  • Use perpendicular sections or elevations when designing the transition to ensure the tray remains aligned with the wall and connected properly to the horizontal run .
  • Verify that the auto-connect system of the cable tray does not revert the vertical section back to horizontal during installation .
  • Always follow manufacturer guidelines and local electrical codes to ensure safety and compliance. By using these specialized fittings and following proper installation practices, horizontal cable trays can be effectively bent or transitioned to vertical runs, maintaining cable integrity and optimizing space along walls or in tight areas .
