How long is a cable tray anti-vibration bracket
Traditionally, it has been recommended to install brackets approximately every 1 to 1. 5 meters along the length of the cable tray. There are factors to consider when determining the appropriate bracket spacing for your installation. 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. One common question that arises during such installations is whether brackets need to be spaced at intervals as close as every 1 meter along the cable tray or if spacing can be increased without compromising safety and integrity. Can be used indoors and outdoors. Cable trays or cable ladders can be mounted both in a lengthwise and a transverse direction beneath previously installed cable sections.
