Marking Flags

Rhino and Presco brand utility marking flags are color-coded marking devices used by utility locating professionals, contractors, and excavation crews to identify and mark underground utilities such as water lines, gas pipes, electrical cables, and telecommunications infrastructure before digging operations. These highly visible vinyl flags meet APWA color standards and feature durable wire stakes that help prevent accidental utility strikes by clearly marking the location and type of buried utilities, ensuring compliance with "Call Before You Dig" regulations and protecting workers and infrastructure during excavation projects.
