Intex 28067E Steel Frame 52" Pool Entry Step Ladder with Secure Non-Slip Steps for Above Ground Outdoor Swimming Pools, Silver

There was a slightly better one I found on Amazon https://a.co/d/07BHhT9h , I used ratchet straps to the pool frame to keep it in place. I got sick of how crappy they all are and built a small deck just for a mounted ladder which had been excellent.
