I use this next to my modular synth to store a host of patch cables (now organized by length).
I fit about 9 patch cables on each rung of the unit so loads of storage for approx 90 patch cables if you need that many)
The only problem is that I have a handful of patch cables which are slightly thicker (they are Eurorack branded) which are very tight to fit into the spaces. I may have to file down one side to give a tiny bit more space. They fit as is but definitely not easy.
Though all my MOOG branded patch cables fit no problem!
But overall I am very happy with the unit - very clean.
