This is exactly what I was expecting. We put it about 4 feet off the ground. Super easy install. We just used longer screws and washers we already had. Just screw all 3 in and done. You could use what they have if you want.  The slide is super fast and bumpy. I have gone down it many times (130lbs on a good day). My brother went down it a couple of times (180lbs) and it buckled a little, but I wouldn't be concerned since it is for kids. I feel like it will last us a long time. Great price!
