The National Marker Company sign clearly informs workers or employees to not enter the place. It is mostly used in front of private properties and in office spaces to enforce safety rules. The legend ?SECURITY NOTICE ? DO NOT ENTER? is printed in legible and bold text to ensure better visibility even from a distance. The rectangular sign is UV resistant, chemical resistant and graffiti proof. The sign has NMC Sign Muscle coating to protect the text against fading, scratches, scuffing, mold, and moisture.
