Arbitrary slant side of the cable tray funnel

The slanted or angled side of a cable tray funnel guides cables smoothly, reduces stress, and maintains proper routing while allowing flexible installation.

Function and Design

The slanted side of a cable tray funnel, often referred to as a "waterfall" or angled sidewall, is designed to funnel cables from one tray section to another without sharp bends or pressure points, which can damage sensitive cables such as fiber optic, PoE, or instrumentation cables. These sidewalls create a continuous pathway that maintains cable integrity and ensures a visually neat installation.

Key Features

Bend Radius: Slanted sidewalls typically accommodate a minimum bend radius, often around 120 degrees, to prevent cable stress. Flexible Installation: Many designs allow tool-free installation, enabling installers to adjust the funnel angle to suit the routing path. Material Considerations: Cable tray funnels are commonly made from steel, stainless steel, or aluminum, with corrosion-resistant finishes for industrial or outdoor environments.

Compatibility: These components are compatible with wire mesh trays, ladder trays, and solid-bottom trays, and can be used for horizontal or vertical routing changes.

Installation Considerations

Ensure the slant angle does not exceed the cable's minimum bend radius to avoid damage. Maintain proper spacing between cables to prevent overcrowding and allow airflow, especially for power or high-current cables. Use support brackets or mounting elements to secure the funnel and prevent sagging or movement under load.

For complex routing, consider T-pieces, crossovers, or reductions to integrate the slanted funnel into the overall tray system.

Standards and Best Practices

Cable tray funnels and slanted sidewalls should comply with BS EN 61537 or equivalent standards, ensuring safe support and accommodation of cables without acting as walkways or load-bearing structures. Proper installation minimizes mechanical stress, maintains electrical performance, and extends cable lifespan. In summary, the arbitrary slant side of a cable tray funnel is a critical design feature that guides cables efficiently, protects them from sharp bends, and integrates seamlessly into cable management systems while adhering to industry standards.
