Covall 18ft Round Above Ground Pool Cover — Green/Black, Heavy-Duty UV-Resistant with Cable & Winch

Covall's 18ft round above ground pool cover is a heavy-duty, UV-resistant winter cover designed to protect 14–15ft round pools from debris, sun damage, and harsh weather while simplifying spring cleanup.

When you close your above ground pool for the season, choosing a durable cover matters. This Covall solid cover is built thicker than standard winter covers and includes UV inhibitors, reinforced material, perimeter grommets, a vinyl-coated steel cable, and a locking winch so the cover stays secure through wind and rain. Its 18‑foot diameter provides the necessary overlap for 14–15ft pools, giving reliable barrier protection until you're ready to reopen.

How will this cover protect my pool over winter?

The Covall cover prevents leaves, dirt, and most rainfall from entering the pool, which reduces algae growth and lowers the amount of cleaning needed in spring. Its reinforced construction resists tearing, and UV inhibitors slow material breakdown from sun exposure.

• Solid barrier design blocks debris and limits sunlight
• Thicker fabric stands up to snow and ponding better than thin covers
• Reinforced edges and grommets minimize tearing at stress points

Is the cover easy to install and stay in place during wind?

Yes — the cover is made for straightforward installation using the included grommets, vinyl-coated steel cable, and a locking winch. The cable-and-winch system tightens the perimeter for a snug fit that resists gusts and keeps the cover centered over the pool.

• Perimeter grommets spaced for even tension
• Vinyl-coated steel cable resists rust and maintains strength
• Locking winch lets you tighten or loosen the fit as needed

Will this cover withstand sun exposure and repeated seasons?

The material includes UV inhibitors to reduce deterioration from sunlight, and the reinforced weave improves tear resistance so the cover lasts longer than standard options. For best longevity, remove accumulated water and heavy snow promptly.

• UV-stabilized material minimizes sun-related damage
• Reinforced construction resists rips and punctures
• Designed for seasonal use across multiple years with proper care

What size pool does the 18ft cover fit, and how much overlap does it provide?

The 18-foot diameter is intended to fit 14–15ft round above ground pools, offering extra overlap to fasten the cover securely to the pool's perimeter. The additional material helps accommodate railings and any small size variations so you can achieve a dependable seal.

• 18ft diameter suits most 14–15ft round pools with overlap
• Extra material gives room to attach cable and winch properly
• Measure your pool diameter before purchase for ideal fit
