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

Using a hot stick and SnapFast™ clamp installation tool (sold separately), SpanMark flags can be installed and removed from the ground or a bucket without interrupting power. Our patented and rugged SnapFast clamp prevents slippage on single or bundled cables, even in a Force 8 gale. 
Choose from two sizes of clamp: 10–70 mm (0.39–2.75 in.) or 4–16 mm (0.16 to 0.63 in.).
