After finding the "instruction photo" on the sales page of it, assembly was easy, but would it kill the manufacturer to include a printout of it? Count your gear - I think the people who make the packaging are kind enough to take a handful of this and a handful of this. I had spare vinyl mounting screws and nuts and square plates, but were missing the screws needed to attach to the door frame. one of the holes that wasn't fully punched. Overall, however, once installed it's just as good as the ones I've seen elsewhere but two or three times more expensive.
