This Pro-Line reflective band accessory (RB1S-PS, Millennium Part #539409) is a factory-installed 1 in or 3 in reflective decal band applied to Rhino-brand marker posts to boost nighttime and low-visibility recognition. Adding reflective bands helps utility and telecom crews spot marker posts identifying buried fiber optic cable and other underground lines from a distance or in headlights, supporting safer locate and excavation work after dark. Available in two width options to match different post styles, this accessory is stocked in Millennium's Marker Posts & Signs category for utility infrastructure projects.
