Swimline PCO837 Round Deluxe Winter Cover - 33 ft Pool Size, 37 ft Cover Size

What This Part Is Used For
This winter cover is used to close and protect a 33 ft round above ground pool during the off-season. The 37 ft cover size provides extra material for securing around the pool perimeter and maintaining full coverage.

Why This Part Matters
Oversized pools collect heavy debris, so proper cover sizing is critical for keeping leaves and dirty runoff out during winter. If the cover is undersized or shifts in wind, contaminants get into the pool and spring opening becomes a bigger cleanup. A correctly sized cover helps protect the liner and reduces algae and staining.
