TWM - SD
his is the original model of the
Spherical Power Line Marker, and still the most popular and
economical. It was designed in the 1960's in cooperation
with the Arkansas Department of Aeronautics and the Arkansas
Division of the Federal Aviation Administration. It has
remained in continuous production, with only minor changes,
since its introduction.
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.
This Marker is appropriate for neutral wires,
guy wires, and conductor wires up to 69KV only.
