Product Specifications

15*21 FT Oval Above Ground Pool Cover — Blue — Ratchet Strap

Product details

At 15*21 ft, you're close to a rectangular footprint with rounded corners, and this blue cover uses section-by-section tensioning to avoid slack building up along the long sides. 420D Oxford fabric is sized to match without weak points from patchwork construction.

Installation Instructions

  1. Position & Align: Lay flat, checking clearance at both curved ends and along the long sides.
  2. Tension the Loop: Tension gradually around the full perimeter.
  3. Release & Store: Flip the release lever to detach.

Usage Tips:

  1. Measure length and width independently — don't scale up from a smaller oval you've owned.
  2. Keep the buckle mechanism free of dirt.
  3. Fold along existing seams.

  • 【Section-by-Section Tensioning】 No single section ends up looser than the rest.
  • 【No Compromise on Fabric Weight】 Same 420D Oxford grade throughout the lineup.
  • 【Solo Installation】 Manageable by one person despite the size.
  • 【Bright Blue Trim】 Livens up a larger oval pool area.

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.
