Don't let factors such as time of day or weather conditions prevent you from advertising your business. This WindPro® sidewalk sign is made to be used outdoors, rain or shine, day or night. Metal poster clips and two 22" x 28" (W x H) lockable UV protected polycarbonate lenses will hold graphics securely. The sidewalk sign features LED illumination with an energy saving or bright mode for easy evening visibility. A rechargable lithium battery is housed inside of a lockable compartment in the base. Wheels on the side take the frustration out of moving this sidewalk sign in and out of the store. Add water to the base to aid in weighing the unit down. Steel spring legs prevent damage by allowing the WindPro® sidewalk sign to flex with the wind. Overall dimensions measure 25" x 29" x 47 3/4" (W x D x H).
