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 from a bright orange flag with a universal symbol for a live line, or a bright yellow flag lettered with "Danger High Voltage". 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

Each SpanMark flag comes with a patented SnapFAST clamp. This clamp is made from weather resistant, high grade plastic with a stainless steel spring mechanism to securely grip single or bundled lines up to 2.5" in diameter. It 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.
