Cable trays typically use three main types of right-angle fittings: horizontal inside, horizontal outside, and vertical bends.

Horizontal Bends

• Inside Horizontal Bend (90° Inside Elbow): Used when the cable tray needs to turn inward around a corner. It maintains the tray's structural integrity while allowing cables to follow a smooth path.
• Outside Horizontal Bend (90° Outside Elbow): Used when the tray needs to turn outward around a corner. This fitting ensures proper cable support and prevents sharp bends that could damage cables.

Vertical Bends

• Vertical Upward Bend: Allows the tray to rise vertically at a 90° angle, useful for transitioning to higher levels or avoiding obstacles.
• Vertical Downward Bend: Allows the tray to descend vertically at a 90° angle, often used to reach lower floors or equipment.

Special Considerations

• Radius of Bend: Right-angle bends can be manufactured with standard or long-radius curves. Long-radius bends reduce stress on cables, especially for fiber optic or sensitive instrumentation cables.
• Material and Tray Type Compatibility: Right-angle fittings are available for ladder, perforated, solid-bottom, and wire mesh trays, ensuring proper fit and load support for each tray type . These right-angle fittings are essential for maintaining cable integrity, proper airflow, and compliance with electrical codes while navigating corners in cable tray installations.
