Marking Whiskers

Presco brand marking whiskers are flexible, thin plastic markers designed to provide highly visible identification of underground utilities and buried infrastructure without obstructing vehicle or pedestrian traffic. These slender, resilient markers can bend when stepped on or driven over and spring back to their upright position, making them ideal for long-term marking of gas lines, water mains, and other buried utilities in areas where traditional rigid markers might be damaged or create safety hazards.
