Cable trays crossing lines

Cable tray crossings allow multiple trays to intersect safely and efficiently, ensuring organized, stable, and standards-compliant cable routing.

What is a Cable Tray Crossing?

A cable tray crossing (also called a cross junction or cross fitting) is a component designed to connect up to four cable trays horizontally in a cross shape. It ensures stable and organized cable routing at intersection points, preventing cable tangling and maintaining accessibility for maintenance or future expansions . These crossings are essential in complex installations where multiple power, data, or control cables intersect.

Materials and Standards

Cable tray crossings are typically made from galvanized steel, providing high load capacity, corrosion resistance, and fire protection. Many products are CE-certified and comply with standards such as DIN 4102-12 (fire resistance E90), ISO 14001, and ISO 45001 . The choice of material may vary depending on the environment, with options including stainless steel, aluminum, or halogen-free plastics for sensitive installations .

Installation

Installation is straightforward and tool-efficient:

1. Insert the cable trays into the crossing at the designated connection points.
2. Secure each side with screws (typically two per side) to create a firm, vibration-resistant joint .
3. Ensure proper alignment to maintain horizontal stability and prevent sagging or stress on cables. Crossings are compatible with standard cable trays, usually with side heights of 60 mm and widths ranging from 100 mm to 300 mm . Proper installation reduces installation time, improves system longevity, and maintains tidy cable routing.

Applications

Cable tray crossings are widely used in:

• Industrial facilities for power and control wiring.
• Commercial buildings for structured cabling and data networks.
• Renovation projects where multiple cable routes intersect.
• Specialized environments like cleanrooms or mobile installations, where organized and interference-free routing is critical .

Benefits

• Organized cable management at intersections.
• High load capacity for heavy power and data cables.
• Fire resistance and corrosion protection for safety and durability.
• Easy maintenance and future-proofing for system expansions.
• Compliance with international standards ensures safety and reliability . Using cable tray crossings ensures that cable networks remain clear, safe, and maintainable, even in complex installations with multiple intersecting lines.
