Fit the brackets first, run the cable and then fit the shelves. I have also removed the plug from the cable, run it in behind the drawers and connected back on previously. I got the black and walnut stuff from a SCP sample sale years ago. Its very classy. Makes a room feel instantly finished IMO
That’s great to know, thanks. Did you have to run the cable before wall mounting? We’re Eyeing up a walnut/black run.
