How to cut a 90° bend in a cable tray

How to cut a 90° bend in a cable tray

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. Construction of a flat 90° bend (A) The amount of tray lip to be removed is equal to 2, 3/4 the width of the tray, half of this measurement will be removed on either side of the centre line. Great if you are new or just forgot how to do it, this easy to follow guide makes it so simple. By applying the following formula you can quickly find the size of cut out section that you need to cut out of the side of.
