Pool Mate 18 x 33 ft Oval Dura-Guard Winter Pool Cover — Heavy-Duty Solid Polyethylene with Winch & 4 ft Overlap

Pool Mate's 18 x 33 ft Classic Dura-Guard Winter Oval Above Ground Pool Cover is a heavy-duty, solid polyethylene winter cover designed to keep snow, ice and debris off your oval above-ground pool throughout the off-season.

This winter cover is built to sit loosely on the water, block precipitation from passing through, and resist UV degradation on the blue topside. Made by Pool Mate with decades of pool-cover experience, it includes a winch and cable system for perimeter attachment and 4 feet of overlap so installation is straightforward. It’s intended for traditional above-ground pools with a standard top rail and is not a summer debris cover.

How durable is this cover and what materials are used?

The Classic Dura-Guard cover uses woven polyethylene with an 8 x 8 scrim and a material weight of approximately 80 g/m², giving it a sturdy feel and reliable tear resistance. Pool Mate builds this cover 18% heavier than the industry standard and heat-seals all seams to improve longevity and seam strength.

• Solid, non-permeable polyethylene that blocks water passage
• 8 x 8 scrim weave for enhanced tear resistance
• Blue UV-coated topside to reduce sun damage
• Heat-sealed seams for improved leak and wear resistance

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

The cover is sized for an 18 x 33 ft pool but includes a 4-foot overlap, so the overall cover dimensions are 22 x 37 ft. That extra material simplifies installation and lets the cover float with some slack; if your pool has an unusually tall top rail, consider choosing the next size up.

• Designed specifically for 18 x 33 ft oval pools with four-foot overlap
• Overall cover size including overlap: 22 x 37 ft
• Float-loose design reduces stress on grommets and cable
• Option to go up a size for oversized top rails or heavy decking

How is the cover secured and how should I install it?

The cover comes with a winch and cable for threading through the perimeter grommets; use the winch to tension the cable and hold the cover in place. For pools with surrounding decks, lay the cover across the deck and anchor with vinyl water weights on top, or run the cable beneath the deck when possible to keep the cover secure.

• Included winch and cable for fastening through grommets
• Use vinyl water weights on decks to keep the cover flat and secure
• Recommended to float loosely—do not over-tighten the cable
• Cover clips and cover wrap sold separately for added security

What winter protection and maintenance can I expect?

This is a solid winter cover that prevents rain and melting snow from entering the pool and helps protect against damage from ice and heavy snowfall. Routine checks during the off-season and using an ice equalizer pillow (sold separately) will help reduce pressure points and prolong the cover’s service life.

• Prevents water, snow and debris from passing into the pool
• Designed to handle heavy snow loads and high-wind conditions
• Periodic removal of heavy snow extends cover life
• Compatible with ice equalizer pillows to reduce ice stress

Who is this for: Pool Mate’s Classic Dura-Guard winter cover is ideal for above-ground pool owners who want a solid, long-lasting winter closure that resists water entry and UV damage. It suits traditional oval pools with standard top rails, homeowners in regions with snow and ice, and anyone who prefers a straightforward installation with included winch and cable. If you need a lightweight summer debris cover or a permeable safety cover, consider alternate products; for winter sealing and durability, this Pool Mate cover is built to perform.
