Finished Right Angle Bend of Cable Tray

A finished 90° bend in a cable tray can be achieved using pre-fabricated elbows or by carefully bending the tray on-site with proper tools and safety measures.

Pre-

Fabricated Fittings

For most installations, pre-fabricated 90° elbows are available in standard sizes and materials such as low-carbon steel, stainless steel, or aluminum alloys. These fittings ensure a smooth bend, maintain structural integrity, and reduce installation time. Adjustable elbows can also be used when space constraints or custom angles are required.

Typical bend radii range from zero (sharp) to 24 inches, depending on cable type and pulling requirements.

On-

Site Bending Techniques

If a pre-fabricated fitting is unavailable, a cable tray can be bent on-site using a cable tray bender, crimping tools, or even a metal bar for small adjustments. Key steps include: Inspection and Preparation: Check the tray for dents, cracks, or defects and clean it thoroughly to remove dirt or moisture. Measurement and Marking: Accurately measure the location of the bend and mark it clearly to ensure precision.

Bending: Use a cable tray bender appropriate for the tray size and material. Manual, hydraulic, or electric benders can be used. For steel trays, crimping or gradual bending with a bar can achieve a smooth 90° bend.

Finishing: Remove any burrs or sharp edges after bending to prevent cable damage and ensure safety.

Material and Safety Considerations

Material: Choose corrosion-resistant materials or coatings suitable for the installation environment. Safety: Always wear PPE, including gloves, goggles, and proper footwear. Use tools according to manufacturer guidelines to avoid injury.

Supports: Additional supports may be required at bends to maintain structural stability and prevent sagging.

Summary

A finished right-angle bend in a cable tray can be achieved either by using pre-fabricated 90° elbows or by careful on-site bending with the right tools and safety precautions. Proper measurement, material selection, and post-bend finishing are essential to ensure a smooth, safe, and functional installation.
