The cover features a solid material that blocks sunlight to prevent algae growth, while a central Enviro-Mesh panel allows rainwater and snowmelt to drain through. This prevents heavy water accumulation on the cover, which is the primary cause of cover damage and sagging.

Yes, this cover is specifically sized for a 21-foot round above-ground pool. It includes the necessary overlap to ensure it can be secured properly around the perimeter.

The cover is constructed with Armorkote, a durable, UV-resistant material designed for long-term use. It also features triple-layer binding and heavy-gauge grommets to provide extra reinforcement against high winds and harsh winter conditions.

The Enviro-Mesh panel is designed to be fine enough to filter out leaves, twigs, and larger debris while letting water pass through. While some fine silt may occasionally pass through, the vast majority of contaminants will stay on top of the cover for easy removal.

The dark underside is designed to block out sunlight completely. By preventing UV rays from reaching the water, it significantly inhibits algae growth, making your pool opening process much easier in the spring.

This cover uses a system of grommets and straps to fasten securely to your pool's structure. Ensure you have the appropriate winch and cable or cover clips, which are typically sold separately, to create a tight, wind-resistant seal.
