Aerial Marker Balls help save lives and protect expensive infrastructure by making power lines and guy wires more visible to low-flying planes and helicopters. Marker Balls are typically used in airport and heliport approach areas and where power lines span long distances crossing canyons, lakes and rivers.

The Model JX is available in four diameters: 9", 12", 20" or 24".

INSTALLATION
This Marker installs easily on any wire 1/8" - 1" (custom wire sizes are available) through the use of two UV resistant neoprene strip bushings installed on the wire to match the diameter of the openings (boss) in the Marker. The Marker is then securely bolted around the wire, clamping down on the bushings.


COLOR OPTIONS
Our standard color is "International Danger Orange;" (U.S. Engineer's Spec. 595-121197 or British STD. 381C-1964-No. 557) however, yellow and white are available as an option. In some cases, these colors prove to be more visible, depending on the surrounding terrain. In some circumstances, such as river and canyon crossings, the FAA recommends an alternating pattern of Orange, Yellow, and White.
