The Patented Guy Wire line marker was formulated to provide maximum contrast and reflectivity above, below, or beside the device. The profile is based on research that found contrast in low light conditions is the most important aspect in alerting birds of hard- to-see guy wires attached to telecommunications towers, power poles, and other guyed structures.
