Create attractive signage that withstands rain, snow, and sun with this Radius-Corner Square Sign Blank. Cut from cellular PVC, it's worked like wood but won't rot, warp, crack, or split. The rounded corners give it a pleasing look. This sign blank measures 26" square and 1" thick. Choose from two popular edge styles: a sharp square edge and a rounded bullnose edge. You can also add a groove-routed frame for added detail.
