The best way to keep sand clean and dry for kids to enjoy is to cover up the pits when they're not in use. This handy universal cover is a large sheet of woven polyethylene material that has markings already on it to outline the shape of all the different sandpit tops available from TP. All you have to do is simply fit the right lines to cut along, create locating holes and secure with the elasticated cords that are supplied. Perfect for if you need to replace your existing cover, or if you buy a set where one is not included.
