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.
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.
This is the marker that has set the standard for decades! Routinely installed by helicopter on hot lines. Spiral wire preform for secure attachment. Superior color retention. 9", 20", 24", 36".
Developed for installation on lines up to 345 kV, our EHV markers have a special coating and other design features to reduce corona effects that can lead to burning or melting with standard markers.
12", 24", 30" & 36" aluminum markers for high kV or high temperature ACSS/ACCR lines rated up to 500 kV or 250° C (482° F). Direct attachment to live line. Lightweight: 36" marker weighs only 20 lbs.
Aluminum marker provides 24/7 illumination with 2 steady red LED lights. Satisfies FAA/ICAO catenary lighting advisories. Installs on 50–2,000 amp conductor—no other power source needed!

This system of proven SpanGuard markers warns low flying pilots and drone operators, who are often inspecting lower power lines, that higher power lines are coming up that will cross their flight path.
Uses our durable and effective SpanGuard markers to make hard-to-see guy lines visible to pilots and birds. Suitable for met towers, smaller radio towers, wind turbine installations, and similar obstructions.
