Alert drivers to the presence of bridges and concrete road barriers with the TD9300 and TD9400 RoadGuide markers. These durable markers are constructed of high impact polymer to provide exceptional flexibility and increased impact resistance. These markers feature a larger molded hole to allow more adhesive to flow through, increasing the bond between marker and barrier. The injection molded markers are designed to bend on impact and return to their original shape, reducing the need to continually replace markers. While the improved design supports better adhesion and facilitates ease of installation, the ability to customize the TD9300 and TD9400 markers makes them the top choice in the field. Both series offer multiple color and reflectivity options, and all reflective sheeting is ASTM 4956.01 compliant.
