Swimline LI2152MGU Round Mystri Gold Unibead Above Ground Liner - 21 ft, 52 in Wall

What This Part Is Used For
This unibead liner is built for 21 ft round above ground pools with 52 in wall height. It locks into the bead receiver track to form the sealed vinyl interior of the pool.

Why This Part Matters
Proper 52 in wall compatibility ensures correct liner tension and bead engagement. If the liner height is wrong, it can pull from the track or stretch unevenly under water load. Installing the correct size protects the wall panels and maintains a smooth finish.
