Diamond Grade™ optics provide superior brightness and angularity

The linear delineation system’s unique mounting techniques enable easy application and allow road crews to complete installation of over a 1000-foot section in about six hours

Permanent or temporary installations

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.
Long-distance recognition

Highly conspicuous fluorescent colors are recognized at greater distances with more accurate color perception than nonfluorescent colored products.¹
