I bought my pool from Swim’n Play which has gone out of business. I need (4) 57 3/4”x 7”Ledges. My pool is the Meridian. I have been looking on line, but I’m not having any luck finding the right size. I don’t care if they don’t match color exactly I just want the size to fit Pool. Pool is in great shape except for inside of a few Ledges. Any suggestions where else to look?
