Swimline 21 ft x 43 ft Oval 54 in Wall Liberty Unibead Above Ground Liner, 25 mil, LI2142654LTU25

This is the Swimline Liberty pattern liner for a 21 ft x 43 ft oval above ground pool with a 54 inch wall, part number LI2142654LTU25, in 25 mil vinyl.

Sizing

The listing records the pool size two ways, as 21 ft x 43 ft and as 21 ft x 42 ft 6 in. Both come from the source data, so measure your own pool wall before you order rather than relying on the size printed on an old liner box.

Unibead and gauge

A unibead liner gives you two ways to hang it. Left as supplied it drops into a standard bead receiver, and folded over it works as a J hook liner, which covers most above ground pools built in the last few decades. The vinyl is 25 mil Perma 25 material, a heavier gauge that stands up better to sun, chemistry and everyday use than the thin liners often supplied with a new pool.
