18"x12" reflective sign meets MUTCD standards
18"x12" sign is made from a heavy-duty, .080" aluminum with an engineer-grade, reflective surface that provides added visibility in low-light conditions. Screen printed with UV-resistant inks to prevent fading. Rustproof sign is made to withstand the harshest weather conditions. Holes punched in the center on the top and bottom allow sign to be mounted on standard U-channel steel posts with holes on 1" centers.
