Calculate the necessary length of material to form elbows, considering the inner radius and degree of the bend to minimize material stress. Calculate V-cut dimensions, bolt positions, slope length, and hanger spacing. SVG diagram for on-site marking. What is the Cable Tray Slope & Fabrication Calculator? The Cable Tray Slope & Fabrication Calculator is a field-ready tool for electrical construction workers who need to quickly calculate. The method for producing bridge bend elbows is as follows: Take a 90-degree cable tray bend elbow as an example, and apply the same principles for 45-degree bends accordingly. The length of the bottom side (bottom diagonal) after bending the cable tray should be equal to the width of the cable. Calculate horizontal, vertical, or compound cable tray offsets based on bend angle, offset distance, and available installation space. Use this tool to estimate sloped section length, horizontal run requirement, cut marks, and installation feasibility. Don't spend the many hours required to do counts and create BOMs for projects, rely on Hubbell's take off.
