Product details

The Swimline LI2154BSU25 is a heavy gauge above ground pool liner in the Boulder Swirl pattern, cut for a 21 foot round pool with a 54 inch wall.

Uni-bead fitting

A unibead liner suits either hanging method. It can drop into a bead receiver track, or the bead can be converted so the liner hangs over the top of the wall as a J hook, which is why one liner covers pools built either way.

Heavy gauge material

Swimline lists this liner as Perma 25 heavy gauge rather than the standard base material. That extra thickness is what stands up to sun, chemistry and the daily wear along the waterline.

Measure the pool before ordering. The wall height and the pool diameter both have to match, since a liner cut for a different size will not seat correctly no matter how it is hung.
