We had to have a welder make a platform box about 5-6” tall and length of the base, then screw in into the concrete. It dipped down just enough thatt when you held it in place, it interfered with the pool sliding. That was a great fix. I’m handicapped and there was nothing to hold onto to get in and out of the pool. I try to do water exercises 3 times a week when the weather allows it. It is perfect and very sturdy for me to use to get in and out of the pool. .
