The Cover Lock system utilizes shock cords sewn into the corners and sides of each cover that simply stretch to fit into the notched corners of the SandLock Sandbox. The elastic cords are also adjustable to allow you to tighten or loosen the tautness of the cover, thereby creating the best fit for your SandLock Sandbox. The appropriate fitment will ensure your cover will remain attached on the windiest of days. SandLock covers also come with patented ventilation panels that allow the air to circulate beneath the cover to deter mold from forming. This is the most innovative and functional design feature that helps maintain a safe play environment for your children.

• SandLock Sandbox covers are the easiest to use and most effective design on the market.
• Each cover incorporates the patented Cover Lock system.

This system allows a single individual to easily remove the cover for access to the sand-play environment, as well as simply put the cover back on for protection from the elements and critters.

• SandLock covers have been thoughtfully designed and thoroughly tested to provide the best protection for your child's sand-play environment.
