So I am thinking about starting a modular synth system soon and was attempting to locate Frack/Euro type rails for building an enclosure for the setup. I can't seem to find these anywhere besides already built into a box surely they are sold somewhere. I basically want to DIY my enclosure as well as the modules and will most likely just source the rails and figure out how to attach them to whatever size/shape enclosure I go for.
Has anyone here ever seen these?
