as you can see from the close-up product picture , the screen have 2 keyhole on either end for wall installation . what you do not see be that the hole be difficult to access . the product ship with 2 bolt that be anchor into the wall first . the anchor be a flimsy type and you have to be careful when you tighten they . the anchor have a threaded end . the screen be then push over the bolt in the wall and secure with 2 nut . this be the part that take I about a hour to complete , and you hear I swearing quite a bit . I use a wrench and pliers to tighten the nut on the anchor bolt , but because the opening on the end of the screen body be so small , I could turn the nut only about 1\/2 notch with either tool . once it be up , thing be much better , and I be please with the overall result .
