Get the whole family involved in the quest for buried treasure by digging in the SandLock 5 x 10-ft. Sandbox with Cover. The long rectangular design fits along a side of your backyard so you can maximize your slice of backyard beach without crowding out your lawn. The six sturdy plastic panels fit together with a precision interlocking design that's easy to assemble and disassemble. A puncture-resistant ground barrier keeps the surf in the box and out of your turf. Featuring SandLock's innovative CoverLock system, the heavy-duty vinyl cover keeps the cats, critters, leaves, and rain out of your pristine sand. Shock cords sewn into each corner of the cover slip under the notches cut into each panel for a tight, secure fit. Four corner seats foster hours of comfortable play and minimize the sand that will be tracked into your house. The seats remove so they can be placed in the center of the box to support the cover in the right position for water run-off.
