By applying the following formula you can quickly find the size of the cut-out section that you need to cut out of the side of the cable tray, or gutter-type section to make that angle. First, you have to find (C) which is found by dividing 90° by (B) 22° = 4. How to calculate cable tray bends? Calculate the minimum required bend radius by multiplying the cable's outside diameter by its bending factor (e. Then, select a standard tray fitting (300mm, 450mm, etc. ) that matches or exceeds this value. Use this tool to estimate sloped section length, horizontal run requirement, cut marks, and installation feasibility.
