The pass-throughs fit perfectly. There's a 3/8" hose barb at the end for running a tube to the kegs, and they all snugged down just fine. I might get a thin piece of wood and put it between the washers and the fridge door, as the plastic was dimpling a little bit, but I was able to get the taps snug without bending it too much, so it might just be fine the way it is.
