Robelle 18 ft Heavy-Duty Winter Pool Cover for Above Ground Pools — Solid Polyethylene, 8x8 Scrim, Winch & Cable

Robelle's 18 ft Heavy Duty Super Winter Pool Cover is a solid, heavy-duty polyethylene winter cover designed to protect above ground pools through the off-season.

When closing an above ground pool for winter you want a cover that resists snow, ice and wind while staying durable year after year. This Robelle Super Winter Pool Cover uses a heavy 8 x 8 scrim and 2.36 oz/yd² polyethylene to deliver reinforced strength and long service life. The cover is solid (non-permeable), features an imperial blue top with a black underside, and includes a four-foot overlap for easier installation plus a winch and cable to secure the perimeter through reinforced grommets.

How strong is this cover and what do the material specs mean?

The cover’s strength comes from two measurable factors: scrim count and material weight. An 8 x 8 scrim refers to the woven thread density that stabilizes the fabric, and the 2.36 oz./yd² polyethylene increases puncture and tear resistance compared with lighter covers.

• 8 x 8 scrim provides structural weave stability and resistance to stretching.
• 2.36 oz./yd² material weight offers greater tear and abrasion resistance.
• Constructed 18% heavier than industry standard for added durability.
• Backed by a 10-year Robelle warranty for long-term protection.

Will this cover fit my pool and how does the overlap work?

The cover is sized to fit an 18 ft round above ground pool and includes a four-foot overlap beyond the listed pool diameter. That extra material makes positioning and anchoring easier, especially if your top rail is standard size; however, if your top rail is unusually tall, you may want to order the next size up so the cover can float without excessive stress.

• Designed for traditional above ground pools with standard top rails.
• 18 ft pool size plus 4 ft overlap equals a 22 ft total cover diameter.
• Float-loose design: cover should rest on the water surface without tight pulling.
• If top rail height is large, consider ordering a larger cover size for a better fit.

How is this installed and secured for winter weather?

Robelle includes a winch and cable so you can thread the cable through the cover grommets and tighten the perimeter for a snug closure. For added security in windy areas, use cover clips, cover wrap, or vinyl water weights on decks (sold separately) to keep the cover in place and protect against uplift and debris.

• Includes winch and cable for securing through reinforced grommets.
• Recommended accessories: cover clips, cover wrap, and deck water weights.
• Install water weights on decks or run cable under partial decks where possible.
• Not intended for season-long debris protection; designed for winter off-season use.

What performance can I expect during snow, ice and high winds?

As a solid cover, water will not pass through the material, so snow and ice remain on top where you can remove or manage it. The heavy scrim and thicker polyethylene give the cover improved resistance to tearing and stress from frozen loads and gusts, while the included winch/cable system stabilizes the perimeter in gusty conditions.

• Solid construction prevents water seep-through during freeze/thaw cycles.
• Heavy-duty fabric tolerates snow weight and ice better than lightweight covers.
• Winch and cable system help resist uplift during strong winds.
• Ice equalizer pillows available separately to reduce ice pressure on pool walls.

Who is this for: The Robelle 18 ft Heavy Duty Super Winter Pool Cover is made for above ground pool owners who want a robust, long-lasting winter closure that resists snow, ice and wind. It suits homeowners with standard top rails who prefer a solid, non-permeable cover backed by a decade-long warranty and professional-grade materials. If you need seasonal debris protection while swimming, choose a different cover — this model is optimized for off-season winter protection and secure, easy installation.
