Installation Notes
- Inspect the pool floor and walls; remove sharp debris and ensure the sand base is smooth before installing.
- Use a proper liner pad and pool cove where recommended to prevent stretching and premature wear.

- If you're unsure on fit or overlap requirements, consult your manual or contact your local store before opening.
PRO TIP
Measure twice. Liners are best confirmed by exact pool size and track type.
Overlap liners are versatile for 48" and 52" walls, but always check for a level pool floor to ensure the material distributes evenly during the fill.
Color/pattern may vary slightly by production run and lighting. Always verify pool measurements and liner type before opening packaging to ensure a valid return if needed.
