COLLIERVILLE, TN – According to company officials, this mantel can take the heat. The non-combustible, fiberglass/cement aggregate mantel shelves are for indoors or out. There are four hand applied finishes that are light-weight (29 to 42 lbs), strong, weather-resistant and easy to hang—48-, 60- and 72-inch lengths. The Fontana and Little River finishes provide a natural wood look and the Graywash and Whitewash lend a contemporary feel (patent pending).
