Don’t let unattractive fixtures spoil the look of your landscaping. This asymmetrical artificial boulder makes an ideal cover for a pond skimmer or septic lid. The fake rock is made of Fiberlite, a durable, all-weather fiberglass composite coated with exterior-grade acrylics for long-lasting beauty. The material can be drilled with a standard drill, so you can insert a hose or wires for even more options. The artificial landscape rock is designed to be wind resistant, so it’ll stay put until you decide to relocate it. Rock has an irregular shape; interior height varies for a more natural look. Weighs about 12 pounds. Every faux rock is hand painted, so each one is unique. Rocks are a blend of tan and gray shades-tan is the dominant color; the degree of tan and gray colors will vary from rocks pictured. NOTE: Interior view of hollow rock is for informational purposes and does not depict this model. Made in USA. 5-year limited warranty.
