The STERLING SEAL SUPPLY pco121523 is a solid winter pool cover designed for above-ground pools with a 12 x 20 foot water surface area. The cover itself measures 15 x 23 inches larger than the pool opening to provide full overlap and secure anchoring around the pool perimeter. Constructed in a solid green configuration, this cover blocks sunlight and debris from entering the pool during seasonal shutdown. It comes complete with grommets, a cable, and a turnbuckle, giving installers and service techs everything needed for a standard above-ground winterization job.
This cover is intended for residential above-ground pool winterization. The solid design prevents light penetration, which reduces algae growth during the off-season and limits the amount of chemical treatment needed when reopening in spring. The included cable and turnbuckle hardware allow the cover to be tensioned and secured tightly around the pool wall. Pool service professionals and experienced DIYers typically install this cover as part of an end-of-season close-out procedure.
Designed as a direct-fit solid winter cover for above-ground pools with a 12 x 20 foot rectangular water surface area. Verify pool shape and dimensions before installation.
Pool service technicians typically install this cover as part of a standard above-ground pool winterization procedure. Lower the water level to the manufacturer-recommended winterization level before placing the cover. Thread the included cable through the perimeter grommets and use the turnbuckle to tension the cable evenly around the pool wall. Inspect grommets for wear each season before reinstalling.
