I'm not much on assembling screens, and better admit, right now, that I didn't put this one together. I wasn't even here for its assembly. I was having work done mounting my new projector in my theater room, and simply asked the installers to also put together the Carada screen, and mount it. I showed them exactly where I wanted it mounted. It couldn't have been too tough a job, for two reasons. First, they charged me less than $100 for the assembly and mounting, and second, because, according to my wife, one guy put it all together, and the 2nd installer just helped with the mounting. In all, (with mostly one person working), it took less than an hour. Sorry I couldn't be more help with the details.
