Our low cost MetMarkers are bright, highly visible spherical cable markers that help pilots and birds avoid potentially fatal collisions with hard-to-see guy lines. MetMarkers also help prevent costly damage and service outages.

MetMarkers Applications
P&R Technologies has been the worldwide leader in power line markers since 1960, and we have extended our expertise to marking the supporting guy lines for met towers, smaller radio towers, wind turbine installations, and similar obstructions. Marking these dangerous obstructions has become increasingly critical as renewable energy markets continue to grow and more pilots and wildlife are put at risk.
We recommend that each guy wire be marked with a MetMarker at 10ft (3m) below the guy ring on the top set of guy wires. To mark for low flying raptors, we recommend an additional set of guy line markers be installed lower on the same guy wires at least 10ft (3m) above the highest point of vegetation.
Features & Specifications
MetMarkers are available in 9" and 20" diameters and in three colors: international orange, yellow, or white. Like our renowned SpanGuard guy line markers, MetMarkers are made of a durable, high tech plastic with a special UV weather cap to ensure long life and brilliant color.
Installation
The guy line markers attach to the cables with U-bolts for easy installation. Includes guy line markers and installation hardware.

P&R Technologies also offers solar powered LED FAA obstruction lighting systems for met towers, as well as industry-standard FireFly bird diverters, which are often required by US Fish and Wildlife.
