Honestly, I had no idea the dorr required assembly. I was a little disappointed but was ok with how the doors looked after assembled. The biggest problem is the chart you provided was a bit confusing to figure out the size of the hardware and doors. Unfortunately the doors are too small width wise and I need the doors to be 4.5" inches wider than they are. I am happ with the delivery and ease of purchase but not very impressed with how to properly select the correct door size and hardware.
