Page 55 of the Rice Signs 2017 Traffic Safety Catalog details the Traffic Cone product line. PVC Traffic Cones come in three standard heights aligned with MUTCD requirements: 18 inch cones (PVCS18) for parking lots and short-duration deployments, 28 inch cones (PVCS28) for streets and low-speed roadways, and 36 inch cones (PVCS36) for highways and high-speed work zones. Each height is available in standard orange or fluorescent Lime green (the lime variant uses the "-Lime" suffix). The "R" suffix indicates the cone ships with a 6 inch reflective collar at the top for night-time visibility. The PVCH36R is a heavy-base 36 inch cone with extra ballast for high-wind locations. Accessories include T-Cap tops and PVC accessories for custom messaging and cone-mounted signage.
