I have a very Un Level concrete floor, I set it on a set of gorrilla racks i purchased from costco. (Metal shelving Unit)I shimmed the legs where needed, That Door is very stout. It will tell you were you are off, Just pick up some wood shims for installing door Jams they are cheap and worth there weight in Gold.
