The Safety Flag Company of America is offering paddle signs as much as four times more reflective than standard signs. The Safety Flag paddle signs feature either High Intensity Retroreflective 3M film, about twice as reflective as standard engineer-grade signs, or Diamond Grade DG3 3M film, about four times as reflective as engineer-grade signs. The paddle signs are octagonal, offered in 14-inch, 18-inch and 24-inch diameters. The smaller sizes are supplied with 10" or 12" wood dowel handles, and the 24-inch size is supplied with either a 60" dowel or an 81", 2-piece PVC handle. Signs are "STOP" on one side and "SLOW" on the other, or "STOP" on both sides.
