Calculation of cable tray angle cut
Calculate horizontal, vertical, or compound cable tray offsets based on bend angle, offset distance, and available installation space. Measure this distance along the straight tray. The Cable Tray Slope & Fabrication Calculator is a field-ready tool for electrical construction workers who need to quickly calculate V-cut dimensions, bolt hole positions, slope length, and hanger spacing for inclined cable tray installations. Select the bend direction (vertical or horizontal). To find the size of the cut in the tray, you divide the distance between the sets by the width of the tray. For instance, 1500 divided by 600 equals 2. That gives the wanted cuit size. You have used your protractor and worked out you need to make a 22° angle in a 600mm cable tray.
