Commonly known as a post reflector, these 3" wide strips bring extra attention to school signs for added safety. Reflective sleeves are .080 panels of aluminum covered with reflective sheeting that attach to sign posts. According to the MUTCD, the reflective sleeve must be at least two inches in width and be placed the full length of the post from the sign to within two feet above the edge of the roadway. The color of the reflective sleeve must match the background color of the sign. Reflective sleeves are available in all MUTCD sign colors, including yellow and fluorescent yellow-green.
