Don't let poor weather conditions prevent you from advertising your business. This double- sided WindPro® sidewalk sign is designed for use outdoors rain or shine. The snap frame opens on all four sides so you can easily insert 30" x 40" (W x H) posters. A clear plastic cover and water wicking around the frame keeps graphics protected. Steel spring legs prevent damage by allowing the WindPro® sidewalk sign to flex as the wind blows. Water or sand can be added to the base to aid in weighing the unit down. Wheels on the side take the frustration out of moving the sidewalk sign in and out of the store.
