Line Markers

Line Markers are above ground, high-visibility signs that identify the approximate location of buried pipelines.  Most pipelines are buried underground.  Line Markers indicate the type of pipeline buried such as; Gas, Natural Gas, High Pressure Pipelines, etc…. and also includes the name and contact information of the company that operates the pipeline.  The main purpose of Line Markers is to alert those who are digging or working in the vicinity of the pipeline and prevent damage.
