Cable tray can be turned at any angle

Cable trays can be turned using standard or adjustable fittings, but the angle is limited by the type of elbow or corner piece used.

Standard and Adjustable Angles

Cable trays are typically designed to accommodate standard angles such as 30°, 45°, 60°, and 90° using pre-fabricated fittings. For situations where these standard angles do not meet installation requirements, adjustable elbows or corner pieces can be used. For example, the RVS elbow joint allows a horizontal orientation change from -90° to +90°, while the SRS adjustable corner piece provides a range of 0° to 75°.

These fittings are inserted into the tray and secured with screws.

Installation Considerations

When turning a cable tray at an angle, it is important to add supports at the bend points to maintain structural integrity and prevent sagging. The radius of curvature for bends is also a factor; typical radii are around 24 inches, but this can vary depending on the tray type and cable load. Following manufacturer guidelines and standards such as CSA/NEMA VE2 ensures safe and reliable installation.

Summary

While cable trays cannot be turned at any arbitrary angle without limitations, using standard or adjustable fittings allows a wide range of directional changes. The exact angle achievable depends on the specific elbow or corner piece, and proper support must be provided at bends to maintain safety and performance.
