Hold back those hillsides with City Classics modular retaining walls. Based on poured-concrete walls used along railroads and highways, these walls feature injection-molded styrene plastic parts molded in a realistic concrete gray color. Each package includes two three-panel 8-9/16" long x 3-1/4" tall sections plus an additional concrete pliaster. Wall sections are easily combined for additional length, or easily cut using a razor saw.
