Our Outdoor Essentials® Giant Gray Boulder is the largest artificial rock we offer. With a height of 31 inches, it’s tall enough to cover objects like telephone pedestals and large pressure tanks. With a length and width of 4-1/2 ft. by 3-1/2 ft., it covers enough surface area to hide irrigation equipment, large septic tank risers and objects of similar size. This rock is hollow so it makes a great substitute for a real rock, and you can move it fairly easily. It is made of durable fiberglass composite and is coated with UV-resistant finish.
