Screwing in the second side to this box was a joke. It's too low to be able to use a standard drill gun, and screwing it in by hand with a stubby philips head was NOT going to happen. I literally got so frustrated I took it out back and smashed it to bits with a hammer. Do not buy this. Get the larger ones. But beware with the bigger ones, the images in the instructions do not match the actual parts of the box.
