Page 44 of the Rice Signs 2017 Traffic Safety Catalog covers Changeable Message Roll-Up Signs — fluorescent orange mesh signs with hook-and-loop overlay panels that let users quickly swap message text (AHEAD, LEFT, RIGHT, etc.) without buying a separate sign. The RP series (RP5, RP10, RP15, RPA, RPB, RPC, RPHM, RPL, RPMI) provides 9 base sign designs, each available in 36 in or 48 in sizes and in three material grades: reflective vinyl (REF) for day-and-night use, vinyl reflective (VR) premium grade, and non-reflective mesh (NR) for day-only and high-wind deployment. The RU-V series (RU13v, RU16v, RU16v2, RU17v, RU19v, RU28v, RU31v, RU4s) adds vinyl-changeable variants of common construction roll-up signs. Each sign deploys on standard RU-series spring-mounted sign stands.
