Its so easy to install about 45 MIN they are custom made for Fountains, they tell you the exact measurements. Then you drill the holes put in the TVK fastners with 3M 5200(like a toggle nut they give you a tool that when you tighten them down it spreads out) It works great and you don't have to worry about leaving it down, and I had some big people climb it before. They run $285 plus shipping and tax, and you can get them in stainless or white powercoat.
