Product Specifications

Product details

At 12x21 ft, this cover manages a longer flat-sided run than most mid-size pools. This blue cover is reinforced for that stretch — even tension along both long sides, sharp-corner reinforcement, fabric that holds structure.

Installation Instructions

  1. Position & Square Up: Check overhang along both long sides.
  2. Tension the Loop: Tighten gradually around the perimeter.
  3. Release & Store: Release the buckle lever to remove.

Usage Tips:

  1. Inspect seams every few weeks.
  2. Tighten fully ahead of high-wind forecasts.
  3. Store the strap loosely coiled.

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.
