3M 3437 Green Micro Prismatic Sheeting Tape is a highly reflective tape which allows you to identify important spaces from a greater distance. The protective sheeting tape helps the labels and signs maintain reflectivity in abrasive conditions. Prismatic tape plays an important role in keeping drivers and workers safe by increasing the visibility of the objects. This hi-vis tape is also ideal for highlighting signs, barricades, and other traffic control devices or to create custom signs for low-light locations.
