How to calculate the slope of cable trays and make bends
Calculate horizontal, vertical, or compound cable tray offsets based on bend angle, offset distance, and available installation space. Calculate V-cut dimensions, bolt positions, slope length, and hanger spacing. SVG diagram for on-site marking. Measure this distance along the straight tray. 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. Pre-fab vs Field Bent: For standard offsets (6, 12, 18 in at 45°), use manufacturer pre-fabricated offset fittings to save. The first one is when you know the angle you want to create and the second is when you want to make a parallel off-set.
