Standard cable tray widths per IEC 61537 and manufacturers' ranges are typically 50, 75, 100, 150, 200, 225, 300, 400, 450, 500, 600, 750, 900, and 1000mm. maintain spacing or to keep cables in place when the tray is ect the minimum bend ra-dius for cables as they exit the bottom of the cable tray. A rung spacing of 6 to 9 inches (150 to 230 mm) is preferable when the cable tray cont d for instrumentation and control applications that require. Ladder cable tray is available in widths of 6, 9, 12, 18, 24, 30, 36, 42 and 48 inches with rung spacings of 6, 9, 12 or 18 inches. These dimensions define the available cross-sectional area for cable installation.
