This spring-mounted sign is built to withstand the elements. The Outdoor Flex Sign with Ballast Base Kit features tool-free assembly, edges that flip open for easy poster changes, a spring-mounted base that allows the sign to gently flex in the wind and two Titan 10 oz. scrim vinyl posters that are protected behind sheets of clear, non-glare acrylic. Your artwork will be printed onto a single side of the vinyl. The ballast base can be filled with water or sand for stability. Wheels on the ballast base make it easy to move. A one-year warranty is also included.
