OptiMA® OptiPrint® Polar Coordinate Boards

OptiPrint® 4' X 4' polar coordinate whiteboards feature a polar grid coordinate board with an exceptional dry erase writing surface. The printed graph includes twelve concentric circles on 1 7/8" centers. The lines to the circumference are 15" apart, and the outside diameter of the polar graph is 45". Users can select from either a 4' Tall X 4' Wide magnetic receptive board, which allows magnets to be used in conjunction with the writing surface, or the non-magnetic version. Both options feature the exact same terrific dry erase writing surface from OptiMA® and a permanent print. The board includes satin anodized aluminum trim and a full-length marker tray. The board ships from the factory in about 3–5 working days with installation hardware. It is not recommended to clean these boards with anything containing ammonia, which is found in most glass cleaners.
