We purchased this ladder to install in our attic space to reach the upper part of our attic, and it works well for that purpose. Install was a little nerve wracking. You have to remove the stairs themselves from the wall bracket to install it, and I suggest taking pictures of the way the bolts are installed before removing anything. We had to purchase some large lag screws due to the size of the holes on the wall bracket. The included installation hardware was for concrete, not wood. The stairs are a little hard to pull down, but work really well. It was shipped in an actual crate, so A for packing.
