Product Specifications

Product Description

12*18 is one of the more common rectangular sizes, often chosen because it fits neatly against a fence line or deck edge in a way round or oval pools can't. The FairCovers cover for this size treats the full rectangular outline as a single tensioned loop, with reinforced corners where the straight sides meet at sharp angles.

About this item

  • 【Fits Against Fences and Decks】 The straight-sided shape this cover protects is popular specifically because it aligns with property lines and deck edges.
  • 【One Continuous Tension Loop】 Rated to an estimated 1,200 lbs, the strap doesn't treat the long and short sides as separate zones.
  • 【Corner-Specific Reinforcement】 Every 90-degree corner gets extra stitching, addressing the stress concentration unique to flat-sided shapes.
  • 【420D Oxford Fabric】 The same weight used throughout our rectangular lineup — no thinning for mid-size pools.
  • 【Debris Doesn't Collect in the Corners】 A tight seal at all four corners prevents the leaf buildup that loosely fitted covers allow.
  • 【Measure Before Ordering】 Rectangular pools from different brands can vary on both length and width even at the same listed size.

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.
