Comes with no fitment other than that shown. The top with two screws holding the hinge is not milled enough to allow for the 13mm head to be tightened. I've tried 1/4", 3/8" and 1/2", 12 point and 6 point sockets. I didn't have a thin enough socket to do this smoothly and after resetting I can Don't use a wrench. I ended up using a 1/2" 12-socket head and hoping I didn't tear the bolt. There is another similar product for $20 cheaper with bolts, if I had seen it first I would have bought it. Holds the door open properly.
