SpanMark Applications

SpanMark warning flags make it quick, easy, and affordable to mark low hanging hot lines near utility facilities, construction sites, or anywhere tall equipment or helicopters might strike a line.

Easy to Install on Hot or Cold Lines

SpanMark installs in seconds from the ground or a bucket. Our patented and rugged SnapFast mounting clamp prevents line slippage on single or bundled cables. It’s also safe to use on OPGW lines. Once in position, the grip is such that the clamp stays in position, even in a Force 8 gale. Using a hot stick equipped with a SnapFast installation tool, SpanMark can be installed on live power lines up to 115 kV. Simply push the unit against the hot or cold line and the clamp snaps shut. The clamp can be quickly removed using the same tool.
