Home / Calculation Specifications of Cable Tray Supports

This step‑by‑step approach helps you determine width, depth, support spacing, and allowable load with confidence. OBO BETTERMANN has offered prod-ucts and solutions for electrical instal-lation for over 100 years. With our many years of experience, we are one of the leading manufacturers in this field. Cable tray support quantity can be calculated using a simple formula: Support Quantity = Total Length ÷ Support Spacing + 1 20 ÷ 2 + 1 = 11 supports In a typical project, a 20-meter cable tray with 2-meter spacing requires 11 supports. All illustrations, descriptions and technical information included in this document are provided as indications and can cable trays are equivalent. In this guide, you will learn how to calculate cable tray size step by step using a practical formula, tray selection rules, and a real example.
