Winter Block 18' Round Blue Above-Ground Winter Pool Cover – Solid Polyethylene

Protect your above-ground pool this winter with this heavy-duty cover from Winter Block.

It's designed for 18-foot round pools, with a generous 3-foot overlap (total cover size is 21x21 ft) to ensure full coverage.

Made from solid blue polyethylene, it blocks out sunlight and debris, keeping your pool clean all season long.

It's lightweight enough to handle (about 6 lbs) but tough enough to last, backed by an 8-year limited warranty.

Close up the pool the right way and make opening day a breeze!
