Page 62 of the Rice Signs 2017 Traffic Safety Catalog covers U-Channel Sign Posts — the most common sign post type for MUTCD signage. U-Channel Posts come in three weight grades calibrated to the wind-loading requirements of the sign size and post height: 1.12 lb/ft for light-duty residential and parking-lot applications, 2 lb/ft for standard street signs, and 3 lb/ft for highway and heavy-duty installations. All posts are pre-punched on 1 inch centers for hardware compatibility with sign mounting and breakaway accessories, and are available in standard galvanized steel finish or green powder-coat for cosmetic intersections. Standard lengths are 6 ft, 7 ft, 8 ft, 10 ft, and 12 ft, with installation kits (P2-GV-SN-KIT6 / P2-GR-SN-KIT6) and breakaway kits (P2-GV-BA6 / P2-GR-BA6) packaging post plus hardware for fast deployment.
