I bought about 20 of these when I decided to make my own patchbays both for live rig and for my studio setup.
Does precisely what it needs to do; use M3 rack screws to fit a 19"-rack backplate with the powercon or XLR-plugs of your choice, fit with optional multicolor Neutrik labeling sheets, and color-coordinate those with optional coding rings for your Neutrik plugs. Pristine rigs for the win!
These are a bit pricy for what it is – and for my personal taste. Color labels, coding rings, adapters set me quite a bit of money. But I don't think there is an equally effective alternative out there, so this is THE way to go.
