3M™ Diamond Grade™ Linear Delineation System

Providing eye-catching reflectivity for drivers’ day or night, their unique crimped design allows for excellent visibility and angularity—even at high entrance angles. They’re fast and easy to install and available in different widths to suit your application.

  • Continuous delineation.

    Creates one continuous reflective line instead of “spot” delineation.

  • Applications include:
    • Construction barriers
    • Curved roadways
    • Guardrails
    • Tunnel approaches
    • Entrance and exit ramps
    • Bridges
