Qunomic Virtual Technology, LLC’s Queue Virtual Line System uses Laser Illumination Technology (LIT) to project a virtual line on any surface. It eliminates the recurring need of replacing chipped and faded painted lines or tape that gets torn quickly under normal wear. Such markings are required to insure warehouse safety under strict OSHA standards. The weatherproof Queue can also be used outdoors to create a visible dock line for trucks as an aid in backing into docks at night. In interior and exterior applications, the Queue provides a virtual line that cannot be worn out or covered up by dirt, debris, rain, snow, ice or fog.
