Page 61 of the Rice Signs 2017 Traffic Safety Catalog begins the Hardware and Posts section with reflective markers and post reflectors. Flexible Markers are surface-mount delineators that bend on impact and return to upright — used as lane delineators in tight spaces. Aluminum Post Reflectors (APR-348 series) attach to existing sign posts to add reflective conspicuity in low-light conditions, with Left, Right, White, and Yellow variants for different lane-marking scenarios. Acrylic Markers are low-profile reflective discs for pavement and curb mounting. Object Markers (OM series, covered in detail on page 6) include OM1, OM2-V, OM3-C/L/R, and OM4 variants for marking roadside hazards, narrow bridges, gore points, and elevated obstructions.
