This one is 21 foot round, 52 inch wall, uni-bead. Measure the pool rather than working from what the box said years ago, and look at how the existing liner attaches at the top of the wall so the bead style matches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstalling it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eLiner changes go best on a warm day, when the vinyl is soft and stretches into the corners instead of fighting you.
