Swimline LI1854ASU Round All Swirl Unibead Above Ground Liner - 18 ft, 54 in Wall

What This Part Is Used For
This unibead liner fits 18 ft round above ground pools with 54 in wall height. It locks into a bead receiver track and creates the internal water barrier. It is used during full liner replacement in residential pool setups.

Why This Part Matters
Deeper wall pools require precise liner height for proper fit and tension. A liner that is too short can tear at seams, while excess material can wrinkle. Correct sizing protects the steel wall and frame from water damage.
