The upscale design, with smooth curved edges gives WindMaster V4 wind-resistant curb signs a contemporary look. The molded round corners add interest and also eliminate corner points. A completely enclosed top provides maximum moisture resistance. The two side rails open to load and unload posters. The top and bottom rails are stationary and cannot be kicked out of place. Choice of two styles -- easy snap on legs or molded water/sand-filled base with built in wheels that tilt and roll for easy moving.
