Robelle 18 x 40 ft Heavy-Duty Oval Winter Pool Cover — Solid Polyethylene, Winch Included

Robelle's 18 x 40 ft Heavy Duty Super Oval Pool Cover is a solid, heavy-duty winter cover engineered to protect above-ground oval pools through the off-season.

When winter arrives, a durable, well-fitting cover keeps leaves, snow and ice off your pool and reduces maintenance come spring. This Robelle Super Winter Pool Cover is a solid polyethylene cover woven with an 8 x 8 scrim and a material weight of 2.36 oz./yd², offering a heavier construction than many standard covers. It arrives in an imperial blue topside with a black underside, includes a winch and cable, and provides a generous four-foot overlap to simplify installation around traditional above-ground top rails.

How does this cover stand up to winter weather and debris?

The Robelle Super Winter Pool Cover is a solid cover that blocks water and debris from passing through the fabric, so leaves, snow and ice stay on top of the cover rather than in your pool. Robust scrim count and material weight increase resistance to tearing and stretching during seasonal freeze-thaw cycles.

• Solid polyethylene construction prevents water penetration through the fabric.
• 8 x 8 scrim provides reinforced weave strength against punctures and wind.
• Material weight of 2.36 oz./yd² (approx. 80 g/m²) for extra durability.
• Designed to hold snow and ice loads while keeping pool water clean.

Will this cover fit my 18 x 40 ft oval above-ground pool and how is it installed?

This cover is sized to fit 18 x 40 ft oval pools with a built-in four-foot overlap; total cover dimensions are approximately 22 x 44 ft to simplify draping and anchoring. It is intended for traditional above-ground pools with standard top rails; for very tall rails choose the next size up to avoid excess stress on the material.

• Includes a winch and cable to secure the cover through perimeter grommets.
• Four-foot overlap reduces trimming and makes placement faster.
• For decks, place the cover over the deck edge and use vinyl water weights.
• Not recommended as a swimming-season debris cover — intended for offseason use only.

What accessories or extra steps improve performance and longevity?

Use the provided winch and cable as the primary anchoring method and consider cover clips or cover wrap for additional attachment in high wind locations. Vinyl water weights work well when part of the cover rests on a deck; ice equalizer pillows (sold separately) can reduce winter pressure on the cover.

• Secure cable through grommets; tension with the included winch.
• Optional cover clips and cover wrap for extra retention in windy areas.
• Place vinyl water weights on top when covering decks or partial decks.
• Consider ice equalizer pillows to protect the pool structure from ice movement.

How long can I expect this cover to last and what warranty is included?

Robelle builds this cover about 18% heavier than typical industry standards, using tested materials and reinforced scrim to extend service life. Robelle supports the product with a 10-year warranty, reflecting the company’s more than five decades of experience manufacturing pool covers.

• Constructed heavier than standard covers for extended durability.
• 8 x 8 scrim and 2.36 oz./yd² polyethylene for long-term resistance.
• Backed by a 10-year warranty for added confidence.

Who is this for: Pool owners with a traditional above-ground oval pool (approx. 18 x 40 ft) who want a robust, solid winter cover that keeps debris and meltwater out of the pool and reduces spring cleanup. Choose the next size up if your pool has unusually large top rails or if you need extra slack for a secure float. This cover is best for off-season protection and should be installed and maintained following Robelle’s recommended anchoring methods.
