Installation Notes
- Inspect the pool floor and walls; remove sharp debris and smooth the sand base before installing.

PRO TIP
Measure twice. Liners are best confirmed by exact pool size and track type.
If your pool is between sizes or has an unconventional wall height, ask us before ordering so you don't end up with a liner that won't seat properly.
Color/pattern may vary slightly by production run and lighting. Always verify pool measurements and liner type before opening packaging.
