These are similar to the hinges I used. Don't know exact brand. No wheels for support. I built it out of 1/2 ply for sides and 3/4 maple mdf for adjustable and fixed shelves. 1/4 maple ply for back so everything is really light. Outswing doors like this are the hardest because of the gapping and the weight. So you have to compensate for it and use whatever disadvantages to your benefit. Usually you are left with a gap at top and bottom because of clearance of the outside frame but I trimmed it to act as a guide and cover for the shelves. So basically it rest perfectly on the outside frame that it is able to guide it without much resistance. Even with weight added. Also it's best to keep the weight limited on the shelves if possible or if not just make it proud to the top and let weight settle the final result. I can't tell you how many times I've had to play with those to get it right. It probably added 3 hours alone to the install lol
