REGMICS 21 ft Above-Ground Winter Pool Cover — 25 ft Actual, Heavy-Duty LDPE with Cable & Ratchet

REGMICS 21 ft round winter pool cover is a heavy-duty above-ground pool protector with extra 4 ft overlap, reinforced grommets, steel-core cable and ratchet winch for a secure winter seal.

Keep leaves, dirt, snow and rain out of your above-ground pool through the off-season with a cover built to resist tearing and UV damage. This 25 ft actual-dimension cover fits pools up to 21 ft and uses a dense 220 g/m² LDPE scrim, upgraded 500D surface coating and reinforced edges to extend service life. The package includes a steel-core cable and an easy ratchet tensioner so you can tighten and remove the cover quickly without extra fixtures.

How durable is this cover for harsh winter weather?

The REGMICS cover is engineered for toughness: a 16 x 16 scrim count in a 220 g/m² fabric core delivers tear resistance and dimensional stability, while the 500D LDPE surface coating fights UV degradation. Double-row reinforced holes with tear-proof design further protect the edge from ripping under load or wind.

• 16 x 16 scrim weave for reduced stretching
• 220 g/m² fabric density for thicker, stronger material
• 500D LDPE coating resists UV and weathering
• Double-row grommets spaced ~3.39" apart for secure anchoring

Will it fit and stay tight on my 21 ft above-ground pool?

This cover measures 25 ft across, giving a 4 ft overlap designed to fit pools up to 21 ft in diameter and allow for a snug edge tuck. The included steel-core cable routes through the double rows of holes and the ratchet tensioner pulls the cover taut so it remains secure around the circumference.

• Actual cover diameter: 25 ft (fits pool ≤21 ft)
• Extra 4 ft overlap for full edge coverage
• Steel-core cable matches cover circumference for consistent fit
• Ratchet tightening design for fast, one-step tensioning

How easy is installation and seasonal removal?

No special hardware or complex steps are required—feed the cable through the pre-punched reinforced holes, position the cover, then tighten with the ratchet winch. The simple design reduces installation time and makes removal straightforward when you open the pool in spring.

• One-step installation with cable and ratchet tighten
• No separate straps, clips, or anchors needed
• Clear hole spacing supports even pull and alignment
• Lightweight enough for two people to handle safely

How does this cover protect water and pool structure?

The inner black bottom surface helps block sunlight to discourage algae growth while keeping debris out, and the dense material sheds rain and snow to reduce load. Reinforced edges and multiple tie points help keep the cover fastened so heavy precipitation and wind won’t easily dislodge it.

• Black inner layer reduces light penetration
• Durable surface coating sheds moisture and resists dirt
• Extra overlap prevents gaps at the rim
• Multiple grommets provide redundancy for security

Who is this for: The REGMICS 21 ft round winter pool cover fits pool owners who want a robust, weather-resistant cover that’s simple to install and built to last. It’s ideal for above-ground pool users facing heavy leaf fall, rain, snow or strong sun who prefer a mechanical cable-and-ratchet fastening system rather than individual clips or stakes. If you need a heavy-duty seasonal barrier with reinforced edges and an extended overlap to ensure full rim coverage, this cover is a practical option.
