Robelle 18 x 33 ft Oval Winter Pool Cover — Value-Line solid polyethylene, includes winch & 3 ft overlap

Robelle's 18 x 33 ft Value-Line Winter Oval Pool Cover is a solid polyethylene winter cover designed to protect traditional above-ground oval pools through the off-season, including a 3-foot overlap and an included winch and cable for secure installation.

When closing an above-ground oval pool for winter, choosing a durable, easy-to-install cover matters. This Robelle Value-Line cover uses a 7 x 7 scrim woven polyethylene at 2.2 oz./yd2, has an azure top and black underside, and comes with a winch and cable sized to tension the cover through perimeter grommets. The 3-foot overlap (making the total cover 21 x 36 ft) simplifies installation and helps the cover sit loosely on the water, while the solid fabric blocks water passage and large debris during the off-season.

How does this cover protect my pool through winter weather?

The solid design stops water from passing through the material, limiting leaves, dirt and sunlight from entering the pool while reducing algae growth potential during storage. Its heavier-than-standard construction and woven scrim improve tear resistance under snow and ice loads.

• Solid polyethylene blocks water and debris from passing through.
• 7 x 7 scrim woven pattern increases tensile strength.
• Constructed about 10% heavier than many industry standards.
• Designed to handle snow and ice when used with proper floatation accessories.

Will this cover fit my 18 x 33 ft above-ground oval pool easily?

Yes — Robelle lists the cover for 18 x 33 ft pools but includes a three-foot overlap so you receive a 21 x 36 ft total cover. That extra material makes draping and securing around standard top rails simpler; however if your pool has unusually large rails you may want to size up.

• Cover listed as 18 x 33 ft with 3 ft overlap around perimeter.
• Overall cover dimensions: 21 x 36 feet including overlap.
• If top rail is oversized, consider ordering the next size up for a looser fit.
• Designed for traditional above-ground pools with a standard top rail.

How do I install and secure the cover so it stays in place?

The cover ships with a winch and cable that thread through the grommets around the cover edge; use the winch to tension the cable and draw the cover snug. For added anchoring, Robelle recommends cover clips and cover wrap (sold separately) or vinyl water bags on decks; avoid other fastening methods that could damage the fabric.

• Includes a winch and cable to secure through the grommets.
• Use cover clips or cover wrap for extra hold (not included).
• For pools with decks, place vinyl water weights on top of cover.
• Allow cover to float loosely — do not overtighten; consider larger size for big rails.

What materials and warranty back this Robelle winter cover?

The cover is woven from polyethylene weighing 2.2 oz./yd2 with a 7 x 7 scrim — indicators of durability and expected lifespan. Robelle constructs this Value-Line cover slightly heavier than typical covers and supports it with an 8-year warranty, reflecting over 50 years of company experience in pool covers.

• Polyethylene fabric, 2.2 oz./yd2 (approx. 74 g/m2).
• 7 x 7 scrim weave for improved strength and stability.
• Manufactured heavier than many standard covers and backed by an 8-year warranty.
• Not intended as a season-long debris cover for swim months — designed for winter/off-season use.

Who is this cover best suited for? Robelle's 18 x 33 ft Value-Line Winter Oval Pool Cover is ideal for owners of traditional above-ground oval pools who need a reliable, solid winter cover with extra overlap to simplify installation. Choose this model if you want a heavier-than-standard polyethylene cover that includes a winch and cable and is backed by a long warranty; if your pool has oversized top rails or unique deck configurations, consider sizing up or adding recommended accessories like cover clips, wrap, or water weights for optimal performance.
