PRO TIP
Measure twice. Liners are best confirmed by exact pool size and track type.
Overlap liners are the most versatile for varyng wall heights, but ensure you have enough coping strips to secure the liner to the wall properly.
Color/pattern may vary slightly by production run and lighting. Always verify pool measurements and liner type before opening packaging as liners cannot be returned once removed from the box.
