Our paper sign holder takes standard 8.5 inches by 11-inch paper. This allows you to print out your own sign and insert it straight into the sign holder. All you need to is slide in the paper in between the 2 pieces of acrylic. To apply all you need to do is screw thread into the stanchion top of any stanchion that supports it. This is only available in crown or flat top stanchion styles, ball top styles cannot be used for signage. Different studs are available for all major brands of stanchions.
