Suitable for transmission lines, SpanGUARD markers have been in service since 1950, secured to the power line by armour rods.
The secret of the SpanGUARD is its unique construction and method of attachment. SpanGUARDs are fastened to the conductor by means of spiral formed armor rods. These spiral rods actually reinforce the conductor at the point of attachment and are completely slip-proof. They are designed to protect the conductor.
SpanGUARDs are the best power line markers
on the market. Each marker is constructed of Rovel ABS, a
material that is long-lasting with good colour retention.
