Power Line Markers

P&R Tech is the worldwide leader in power line markers and related safety products for the utilities industry. We introduced our original SpanGuard spherical power line markers in 1960, and many of them remain in service to this day, warning pilots of wires in their flight path.

Our products include the industry’s most trusted overhead wire marker, along with the aerial markerball and other types of aerial line marker designed to enhance visibility and safety. You’ll find our markers on transmission lines, river crossings, and anywhere aerial hazard marking is critical.

Over the years, we improved our marker design and extended it to a variety of models that fit nearly any application and budget—from our low cost Redball markers to aluminum markers that attach to today’s high temperature lines.

Talk to us about your application. We can help match the right markers with the job, provide the necessary quote, coordinate with your project schedule, and as needed, arrange helicopter installation.
