Thanks for the height clarification. My bead is not the J hook type; it is a fatter version of the standard bead that was apparently used for the Esther Williams and Johnny Weissmuller pools that were made by Delair group LLC. They sold the pool portion of their holdings somewhere around 2010, I think. I did not want to purchase the wrong size liner and have too much or too little material to deal with! My sister gave me the pool and I relocated it last weekend. I am cleaning up all of the components and still deciding on the location. I figured that I wanted to get the liner ordered so that it would be here when I need it. Thanks again!
