Product Specifications

21 FT Round Pool Cover — Black — Ratchet Strap

Product Description

21 ft is a less common pool size, which makes getting the fit right even more important. The FairCovers 21 FT Round Pool Cover is reinforced specifically for larger surface coverage, with a ratchet strap rated windproof to 80 mph — because a loose cover at this size can genuinely cause damage in a storm, not just blow around the yard. Reinforced seams and a high-tension closure are built to handle that added stress.

About this item

【21FT Is a Less Common Size — Measure First】 Double-check your pool's exact diameter before ordering, and size up if you're between our 20ft and 22ft listings, to ensure the best fit.
【Windproof to 80 MPH】 This matters more at 21 ft than on smaller covers — a loose cover this size can genuinely cause damage during a storm, not just blow around the yard.
【Reinforced Seam Construction】 Extra stitching runs exactly where larger covers tend to wear first, extending the usable life of the cover across repeated seasons.
【High-Tension Closure】 Estimated at 1,200+ lbs of holding strength, keeping the cover locked down regardless of gust strength or duration.
【Effective Debris Barrier】 Blocks leaves and dirt across a large surface area, keeping water noticeably cleaner between uses compared to an unsealed or loosely-fitted cover.
【Compact Off-Season Storage】 The included storage bag keeps the strap and folded cover organized and protected when the pool is in use.

Q&A

Q1: Is this pool cover waterproof? Will it block leaves and debris?

A: Yes, absolutely. Our pool covers are engineered from heavy-duty, commercial-grade waterproof and UV-resistant fabric with reinforced seams. It provides a 100% barrier against rain, falling leaves, dust, and debris, keeping your pool water crystal clear and reducing evaporation when not in use.

Q2: Will the cover blow away in high winds? How does it stay secured?

A: Not at all. To withstand harsh weather, our pool covers feature reinforced, rust-proof heavy-duty grommets combined with high-elastic windproof drawstrings (or a heavy-duty water bag/anchor system, depending on the model). The double-stitched overlapping hems ensure a snug, wind-resistant fit that stays securely in place even during severe storms.

Q3: How do I clean and store the pool cover properly?

A: Maintenance is simple. Just hose off any dirt or leaves, and gently scrub with a soft brush and mild soapy water if needed (avoid harsh chemicals or machine washing). Crucially, make sure the cover is completely dry before folding and storing it in a cool, dry place to prevent mold or mildew growth.
