[pdf] Creating a 90-degree elbow in an electrical cable tray, often called a "fabricated" or "mitered" bend, involves cutting, bending, and fastening a straight section of tray. The most common method involves creating two 45-degree cuts to form a 90-degree angle. The length of the bottom side (bottom diagonal) after bending the cable tray should be equal to the width of the cable. Professional Cable Tray Elbow Making | Metal Fabrication Tutorial Learn how to make cable tray elbows professionally with step-by-step guidance. Determine the angle and required radius size of the elbow, and choose the appropriate elbow type based on these parameters, such as 90 degree elbow, 45 degree elbow, etc. Ladder cable trays are critical.
