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. Choose either bright orange or yellow with either a universal symbol for a live line or "Danger High Voltage" lettering. Other colors, symbols, wording, and numbering are available by special order. SpanMark flags are 13.375" x 11.5" and made from a durable, flexible vinyl material.

Easy Installation

SpanMark can be installed and removed from the ground without interrupting power. Our durable and patented SnapFast mounting clamp securely prevents line slippage on single or bundled cables 0.375"–2.75" in diameter. (Clamp for smaller lines available by special order.)

The SnapFast clamp installs in seconds from the ground or a bucket using a hot stick equipped with a SnapFast installation tool. Simply push the unit up against the hot or cold line and the clamp snaps shut. The clamp can be quickly removed using the same tool. Once in position, the grip is such that the SpanMark stays in position, even in a Force 8 gale.
