The NatureROCKS Large Dark Gray Granite Boulder Is a massive climbing structure which gives any outdoor space a rugged appearance. It is 8 feet tall at its highest point, with a 9.5 by 7.25 foot base. It is so realistically detailed that it can easily be taken for granite. However, it is actually high quality glass fiber reinforced concrete that is carefully modeled to look like a rocky outcropping. The surface has a rough, hand painted finish with plenty of convenient ledges and crags for kids to hang on to as they climb, and a flat top for them to stand or sit on. Because of its size, this structure is recommended for children over the age of five, and should always be surrounded by approved safety surfacing. It is recommended that the Large Granite Boulder be installed near other NatureROCKS dark gray granite boulders and net climbers to complete the appearance of a rocky landscape.
