What Is the “U” in 2U Cable Manager?

What’s the difference between 1U and 2U cable managers? The most distinguishable one in my mind, is the number lying in their name. The “U”, also known as “RU”, stands for rack unit that is a unit of measure defined as 44.50 millimeters (1.75 in) by EIA. It is most frequently used as a measurement of the overall height of 19-inch and 23-inch rack frames, as well as the height of equipment that mounts in these frames. With this standard, we don’t need to play with complicated numbers, instead, a simple addition can work. For example, a 12U cabinet can accommodate twelve 1U devices or six 2U devices or four 3U devices. And so on.
