The Ace Eco Outdoor Sign is a foldable A-frame sign ideal for use curbside, near storefronts, on sidewalks and more. The Ace Eco features an aluminum frame that holds two rigid boards. Choose from printed 6mm PVC boards or dry-erase boards or both! Simply open the frame, straighten the arms on the sides, and slide the boards into the frame at the top. Dry erase boards allow for messages that can be easily added, changed or removed!
