The National Marker Company sign informs employees or visitors about a restricted area and that only authorized persons are permitted to enter. It is mostly used in front of private properties, areas with potential hazards to ensure privacy and safety. The legend ?RESTRICTED AREA ? ONLY AUTHORIZED PERSONS TO ENTER THIS AREA? is printed in legible and bold text to ensure better visibility even from a distance. The rectangular OSHA sign is UV resistant, chemical resistant and graffiti proof. It also has NMC Sign Muscle coating to protect the text and graphic against fading, scratches, scuffing, mold, and moisture.
