Bottom rail

I want to make sure I’m ordering the right parts. I need a bottom rail that the side wall inserts into. It is a 24’x4’ round above ground pool roughly 8-10 yrs old. The channel measures 48-1/8" in length on outside diameter.

Thank you for contacting Inyo. Can you post a picture of the top cap, top plate, and bottom plate? That will help us ID the pool.
