POOLHACKER 18x33 ft Oval Pool Cover - 420D Extra-Thick Winter Cover, Cable & Pulley Anchoring

POOLHACKER's 18x33 FT Oval Pool Cover is a heavy-duty 420D winter cover (22' x 37') built to securely protect 18' x 33' above-ground oval pools from debris, sun damage, and cold down to -13°F (-25°C).

This oversized, extra-thick pool cover combines reinforced 160g/m² 14×14 scrim fabric with an upgraded cable-and-pulley anchor so you can fasten a snug, weather-resistant shield across an oval above-ground pool. Designed for a 4-foot overlap, the cover works with metal-frame and steel-wall pools to block leaves, dirt, and rain while resisting tearing and fading from UV exposure. It’s meant for seasonal protection — easy to install, durable in cold conditions, and low-maintenance once in place.

How does this cover stay tight on my pool during windy or snowy weather?

The POOLHACKER cover uses an enhanced cable-pulley system that pulls the perimeter evenly and locks the fabric down so the cover doesn’t billow or shift. The pulley provides simple, mechanical tension while the heavy-duty cable runs through reinforced hems to resist stretching.

• Upgraded cable-and-pulley fastener for consistent tension across the oval shape
• Reinforced hems and strong attachment points to prevent fabric slippage
• 4-foot overlap for extra anchoring and easier staking to the ground
• Designed to shed light snow and route water away using the overlap and drain points

Will this cover survive cold winters and sun exposure?

The material is engineered to stay flexible in freezing temperatures down to about -13°F (-25°C) and includes UV protection to slow fading and degradation from sunlight. Its 160g/m² density with a 14×14 scrim weave adds tear resistance for longer seasonal life.

• Cold-tested to withstand subzero temperatures without cracking
• UV-resistant coating that reduces sun-driven fabric breakdown
• 420D extra-thick construction for increased puncture and abrasion resistance
• 14×14 scrim reinforcement for dimensional stability and strength

How well does it keep debris and maintenance needs down?

With full coverage over the pool and a wide overlap, the cover prevents leaves, dirt, and rain from contaminating your water, which lowers cleanup and chemical use when reopening. The robust fabric and secure fastening also reduce gaps where debris might enter.

• Blocks leaves, seed pods, and general yard debris effectively
• Helps minimize rain dilution and organic build-up while closed
• Smoother reopening with less vacuuming and skimming required
• Compatible with above-ground pool shapes for comprehensive protection

What pool sizes and types is this cover compatible with?

This cover is cut to 22' x 37' overall and is intended to fit 18' x 33' oval above-ground pools, offering about a 4-foot overlap around the rim for fastening. It is suitable for pools with metal frames or steel walls, providing universal seasonal coverage for common above-ground designs.

• Designed specifically for 18' x 33' oval above-ground pools
• Overall cover dimension: 22' x 37' with 4' overlap for secure attachment
• Works with metal-frame and steel-wall above-ground pool constructions
