3M 15" Diameter Full-Range Marker

Full Range markers are ideally suited for marking the location of utilities buried at a deep distance. Passive full range markers will provide accurate identification of buried power lines, helping to reduce the risk of accidentally excavating other buried facilities. All markers function without the need for an external power source. Their water resistant polyethylene shells are impervious to minerals, chemicals and the temperature extremes normally found underground.

• Positive identification of underground assets
• No external power source needed
• Resistant to elements
• Color conforms to APWA standards
