A cable tray straight through funnel is a formed fitting that guides cables from a straight tray section into a controlled exit or branch, ensuring organized routing and reduced mechanical stress.

Purpose and Function

A straight through funnel, also known as an outlet funnel, is used to transition cables from a straight tray section to a new path—either downward, sideways, or into a branch—while maintaining proper bending radii and minimizing mechanical stress on the cables . It ensures that cable bundles exit the tray in a controlled manner, preventing tight bends and potential damage.

Applications

• Vertical routing: Transitioning from horizontal tray runs to lower or higher cable routes.
• Branched runs: Ideal for T-branches or distributing power and data cables.
• Industrial and commercial installations: Used in control cabinets, production halls, workshops, and public facilities for structured cable management .
• Mechanical and plant engineering: Provides robust, traceable cable routing in technical installations.

Design Considerations

• Material: Funnels are typically made of metal or steel for durability in demanding environments .
• Compatibility: The funnel's width, height, and design must match the existing cable tray to ensure proper fit and function.
• Installation: Funnels simplify installation by clearly defining cable routes and connection points, improving clarity in complex, branched systems .

Integration with Straight Cable Trays

Straight cable tray sections, such as those offered in stainless steel or aluminum, provide the main horizontal or vertical path for cables . The straight through funnel connects directly to these sections, allowing cables to exit or branch without sharp bends. Accessories like straight connectors, clamp connectors, and drop-outs can be used to join trays and relieve stress on cables as they exit the funnel .

Benefits

• Organized cable routing: Cables are guided cleanly and predictably.
• Cable protection: Reduces mechanical stress and prevents tight deflections.
• Flexibility: Supports changes in direction, vertical transitions, and branching.
• Ease of installation: Clearly defined paths simplify planning and reduce installation errors . Using a straight through funnel in a cable tray system ensures efficient, safe, and professional cable management, particularly in complex or heavily branched installations.
