This spring-mounted sign is built to withstand the elements. Your artwork will be printed single-sided on Titan 10 oz. scrim vinyl; two posters per kit. Posters are protected behind sheets of clear, non-glare acrylic. Tool-free assembly. Edges flip open for easy poster changes. Spring-mounted base allows the sign to gently flex in the wind. Ballast base can be filled with water or sand for stability. Wheels on the ballast base make it easy to move. One-year warranty.
