Sterling Seal Supply pco121824 Oval Pool Winter Cover 15x21

Product Description

The STERLING SEAL SUPPLY pco121824 is a solid winter cover designed for 15-foot by 21-foot oval above-ground pools. The cover measures 18 feet by 24 feet in actual cover size, providing an overlap margin that secures around the pool wall for a tight fit during off-season storage. Constructed in green, this solid-style cover blocks sunlight and debris from entering the pool water. It ships with grommets, cable, and a turnbuckle, giving installers everything needed to anchor the cover in place without sourcing additional hardware.

This cover is intended for residential above-ground oval pool winterization. It is suited for seasonal climates where pools are closed for extended periods. The solid construction prevents light penetration, which reduces algae growth and keeps the water cleaner through the winter months. Pool service professionals and homeowners completing seasonal closings are the primary installers. The included cable and turnbuckle system threads through the perimeter grommets to cinch the cover securely against wind and weather.

Installation Notes

Pool winterization covers are typically installed by pool service technicians or experienced homeowners as part of a seasonal closing procedure. Before installing, lower the water level to the manufacturer-recommended winterization depth and complete all chemical balancing and equipment blowout steps. Thread the included cable through the perimeter grommets and tighten the turnbuckle until the cover is snug against the pool wall. Avoid over-tightening the turnbuckle, as excessive tension can stress the grommets and tear the cover material.
