Hello - I have a 19 year old above ground 27' round 54" wall with steel top rails - the rails are slanted on the ends - 56" on one side and 57" on the other and 7 3/4" wide - 18 rails total. I have no idea what "brand" the pool is. There is a deck surrounding it so I'm writing to see if there is any way to avoid crawling under there and trying to take pics. 
Thanks for your time,
Kathy
