When playtime ends, protect your SandLock sandbox by using the SandLock Sandbox Vinyl Cover. The durable cover is made from solid vinyl material, and the unique CoverLock system features a patented design with a 5/16-inch shock cord sewn into the inside of each corner for long life. This allows the cover to be stretched over the entire sandbox. Used in conjunction with the removable seats, the cover pulls securely to the corners of the sandbox and is supported in the center with the seats. This cover provides a simple yet effective way to keep your sand clean, dry, and free from animals without worrying about standing water. The cover carries a 10-year limited guarantee.
