High‑quality cable flags and marker flags for utility, telecom, fiber optic and electrical installations. Durable, customizable cable flag markers improve site safety and cable identification for contractors, engineers and utility companies.
A Cable Flag is a high‑visibility marker flag used for identifying underground utilities, buried cables, fiber optic lines, and electrical or telecommunication infrastructure. These cable marker flags are essential for construction, utility, OSP (Outside Plant) engineering, and telecommunication projects to clearly indicate cable locations, reduce digging risk, and ensure safety compliance on work sites.
Our cable flag products are designed to offer long‑lasting visibility and rugged performance in a variety of field environments. Typically made from weather‑resistant PVC or vinyl materials and mounted on wire staffs or stakes, these flags help utility, telecom and construction professionals mark cable routes, boundaries and buried lines. They can be pre‑printed with caution messages or custom text for fiber optic, electrical power, gas or communication lines.
Typical B2B Use Cases:
Utility and telecom network installations
Fiber optic cable burial marking
Underground electrical and power line marking
Construction site safety and cable route indication
OSP, maintenance and inspection crews
Manufactured with bright, eye‑catching colors and clear marking text to improve site safety and regulatory compliance in construction and utility zones.
Flags are made from durable PVC or vinyl that resists fading, water damage, and UV exposure for long‑term outdoor use.

A cable flag is typically installed by inserting the flag staff or stake into the ground directly above or adjacent to underground lines or routes. The flag’s bright colors and printed warning messages provide visual cues to workers and equipment operators, signaling the presence of buried infrastructure. This reduces accidental line cuts, service disruptions, and safety incidents.
