Swimline LI1854MGU25 Round Mystri Gold Unibead Above Ground Liner - 18 ft, 54 in Wall

What This Part Is Used For
This unibead liner replaces the interior vinyl surface of an 18 ft round above ground pool with 54 in wall height. It locks into a bead receiver track and retains water inside the steel wall structure. It is used during complete liner replacement projects.

Why This Part Matters
Proper wall height matching prevents liner stress and seam damage. A failed liner can cause water loss and compromise the pool wall. Selecting the correct bead style ensures secure installation and clean top rail appearance.
