The 18" or 24" two-sided stop/slow sign is made of aluminum with a high intensity, highly visible reflective sheeting. It fits on top of the white pvc 81” pole (72" from the sign bottom) that disassemblies into 2 pieces for easy portability and storage. Each piece of the pole screws securely together. The top piece is 21" and the bottom is 60". The top can be used seperately with a stop/slow sign as a paddle. The pole has mounting holes on the top that accept ¼” bolts for attaching the sign (hardware included). Both the sign and pole meet MUTCD standards.
