Utility markers are needed to bring attention to an underground line. This can be a drain pipe, power line, or a fiber optic cable. Regardless of what is underground, someone digging into your ground could break the line or, worse, become electrocuted. As a result, such utility lines need to be labeled, and our store has several options for this. One of the more common ways is with a utility pole indicating the line underground. Other options include utility tape and flags. All types of markers vary in color, including blue, red, brown, and other shades to draw attention to your utility line.
