Swimline PCO1425 Round Super Deluxe Winter Cover - 21 ft Pool Size, 25 ft Cover Size

What This Part Is Used For
This winter cover is used to close and protect a 21 ft round above ground pool during the off-season. The 25 ft cover size provides extra material for securing around the pool perimeter and maintaining full coverage.

Why This Part Matters
A properly fitted winter cover keeps leaves and debris out and helps reduce algae and staining while the pool is closed. If the cover is undersized or worn, wind can lift it and let dirty water and debris into the pool. Correct sizing helps keep spring opening cleaner and more predictable.
