Robelle Winter Pool Cover for Above-Ground Pools 21 ft — Solid 3 ft Overlap, Winch & Cable Included

This winter cover is engineered to keep leaves, snow and ice away from your above-ground pool during the off-season. Made from 2.2 oz/yd2 polyethylene woven with a 7x7 scrim, the cover combines a durable build with a user-friendly fit: an azure blue top, black underside, and three feet of overlap so it extends beyond the pool edge. Robelle includes a winch and cable to secure the perimeter through reinforced grommets and recommends optional clips or wrap for additional fastening.

How will this cover stand up to winter weather?

The solid material stops precipitation from passing through, reducing contamination and the need for mid-winter maintenance. The 7x7 scrim and slightly heavier-than-standard polyethylene give the cover extra tear resistance and longevity for seasonal use.

• Solid, non-porous polyethylene blocks water and debris from entering pool water.
• 7 x 7 woven scrim increases tensile strength and puncture resistance.
• Constructed about 10% heavier than many competitors for added durability.
• Designed to float freely on the water to accommodate snow and ice loads.

What installation parts are included and how do I secure the cover?

The cover ships with a winch and cable to thread through the reinforced grommets and pull the cover taut around the pool. For extra hold — especially for decks or high-wind locations — Robelle recommends cover clips and cover wrap, which are sold separately.

• Included winch and cable secure the perimeter through grommets.
• Three-foot overlap gives extra material to fasten over a variety of top rails.
• Use water weights on decks when installing over partial or full decking.
• Optional cover clips and wrap improve anchoring in windy areas.

Will this cover fit my above-ground pool and how do I choose the right size?

Order by the pool diameter; the listed size is the pool size, and the cover adds a three-foot overlap (so a 21 ft cover measures 24 ft overall). If your pool has an oversized top rail or a raised deck, consider sizing up to ensure the cover floats without strain.

• Designed for traditional above-ground pools with standard top rails.
• Three-foot overlap included — 21 ft cover equals 24 ft total material across.
• Choose a larger size if your top rail is unusually high or wide.
• Floatable fit prevents excessive stress on grommets and fabric when frozen.

How does Robelle’s warranty and experience affect my purchase decision?

Robelle has supplied pool covers since 1973 and backs this Value-Line cover with an eight-year warranty, indicating confidence in materials and manufacturing. That warranty, combined with a slightly heavier construction than the industry norm, gives buyers greater peace of mind for seasonal protection.

• Robelle has over 50 years of pool cover experience and product support.
• 8-year limited warranty covers manufacturing faults under normal use.
• Material weight and scrim chosen for practical longevity across seasons.
• Not intended for regular-season debris use — designed for off-season closure only.

Who is this for? The Robelle 21 ft Value-Line Winter Pool Cover suits above-ground pool owners who want a straightforward, heavy-duty winter closing solution without specialty features. It's ideal for those with traditional top rails seeking a solid cover that blocks water and debris, includes installation hardware, and is backed by a long warranty. If you need a seasonal, reliable cover that’s easy to secure with a winch and cable and performs well in snowy or windy climates, this Robelle cover is a practical choice.
