This is a MUCH higher quality product than I had anticipated!  It helps if you understand how the door mount hinges work.  I have used them before, so i knew how to install and adjust them so the door gaps are perfect.  We left ours clear, and only used three coats of water based polyurethane to finish inside and out to match our sliding barn doors in our house.  It is screwed to the wall so it cant tip, as it holds about 50 bottles of my bourbon!
