The Bestway Flowclear Ground Cloth for 12 ft. Pools is designed to protect your above-ground pool from wear and tear caused by pebbly turf, pointy twigs and other ground debris. The ground cloths are simply placed on the spot you plan to set up your Bestway pool. One of the benefits of the ground cloths is that they offer fantastic protection for your lawn. If water spills over the edge of the pool, it simply accumulates on the surface, saving you from sinking knee deep in sludge when you exit your Bestway pool. This ground cloth fits 3.66 m (12 ft.) Fast Set Pools and 3.66 m (12 ft.) Steel Pro Frame Pools. WARNING: CHOKING HAZARD -- Small parts. Not for children under 3 years. Shop more pool supplies and accessories from Bestway today!
