What are the types of elbows in Dutch cable trays
These fittings come in two main types: Horizontal Elbows are used for turns on the same flat plane, typically available at 45 deg or 90 deg. Vertical Elbows (often called risers) are used when the cable path needs to change elevation, guiding the tray either upward. The main types of accessories are categorized by their function: Fittings change the path or size of the run, including Elbows (for horizontal or vertical direction changes), Tees and Crosses (for multi-directional junctions), and Reducers (to transition between different tray widths).
