Accidental cable strikes during site digging cause costly power outages, expensive repairs, and severe safety hazards for workers. Installing clear, permanent surface markers along underground HT, LT, and optical fiber runs is essential for workplace safety and municipal compliance. We manufacture durable Cast Iron and GI Cable Route Markers clearly cast with labels for HT Cable, LT Cable, OFC, and DC Solar lines. Built for direct embedding in concrete, these markers withstand heavy traffic and weather without wearing away. ✉️ Need custom-cast lettering or standard markers?
