The 21' Round Crystal Wave Uni-Bead liner is the perfect liner for giving your above ground pool that in ground pool look and feel. The Uni-Bead liner does not require a bead receiver because it actually has a bead receiver built into the liner. The edge of the liner will simply "hook" onto the top of the pool wall for fast, easy, simple installation.
All 52" Uni-Bead liners are specifically made to fit only one size of pool, which means no more unsightly, algae collecting wrinkles in the bottom of the pool. No more tugging and pulling the liner trying to get that exact fit like an overlap liner. Instead do it right the first time with a 52" uni-bead liner. Do it once and be done!
