GLI Gray Promesh Pool Safety Cover – Rectangle 18' × 36'

Protect your rectangular in-ground pool with a breathable, durable safety cover built for reliability and long seasons of use. The GLI 20-1836RE-CES48-PRM-GRY in Gray Promesh fabric is precisely sized for an 18 ft × 36 ft pool, offering a smart blend of safety, practicality, and low-maintenance care that busy households value.

Promesh fabric: safety meets drainage

The distinctive Promesh mesh provides a crucial balance: it keeps out debris and prevents unauthorized access, while allowing rainwater to drain through instead of pooling on the surface. This reduces the weight load you have to manage during removal and minimizes the risk of standing water, helping protect pool chemistry and equipment from excess moisture.

Custom fit for 18' × 36' rectangular pools

Designed around standard rectangular dimensions, this cover delivers a snug, secure fit that respects the geometry of your pool. The gray Promesh color blends with outdoor environments, concealing minor wear and dirt for a cleaner, more polished backyard aesthetic during the off-season.

Durable construction for seasons of use

Reinforced seams and perimeter construction are engineered to withstand harsh weather and repeated seasonal use. UV-stabilized Promesh fabric resists sun damage, extending the life of the cover year after year while maintaining its appearance and effectiveness.

Safety, ease, and everyday practicality

Beyond safeguarding children and pets, this cover reduces the amount of debris that reaches your pool when closed, lowering maintenance time come spring. Its lighter weight compared with solid, heavy-duty covers makes removal and storage easier for homeowners and service professionals alike.

Ideal use cases

• Winterizing an 18' × 36' rectangular pool with dependable safety and debris control
• Seasonal protection that keeps yard debris out of the water while preserving water quality
• Low-maintenance pool care during the off-season with a cover that’s easier to handle

Installation and care tips

For best results, professional installation is recommended to ensure a secure fit with perimeter anchors and straps. Regular maintenance includes rinsing the fabric with mild soap and water as needed and removing accumulated debris after storms to maintain airflow and performance.
