Sandboxes from SandLock bring sand fun to your commercial and residential playgrounds in just minutes. Each sandbox package includes the sandbox, a strong vinyl cover, sandbox seats, and more! The sandbox panels are pre-cut and slot together easily, forming the sandbox walls. The panels are made from commercial grade solid plastic (HDPE), so you won't have to worry about splinters or rust. The panel composition also contains UV stabilizers. Every sandbox package includes a strong vinyl sandbox cover. All of the SandLock sandboxes include at least 2 mini-chairs for kids to sit in. Every sandbox comes with a limited 10-year warranty. Every size of sandbox ships via UPS -- order any one of them online through our shopping basket.
