| SD Series Wire Marker |
 |
 This
is the original model of the Spherical Marker, and still the most popular
and economical. It was designed in the 1960s in cooperation with the
Arkansas Department of Aeronautics and Arkansas Division of the Federal
Aviation Administration. It has remained in continuous production, with
only minor changes, since its introduction. |
 The SD
Marker installs easily on any wire .2" - .875" 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 the bushings.
