TM-2000 Series Detectable Warning Tape System
Four utility-specific models. One integrated system. Engineered for water infrastructure that needs to be found.
Purpose-built for water infrastructure.
The TM-2000 Series combines APWA-standard color-coded warning tape with Armor-protected RF electronic markers — giving excavators both a visual warning at the trench face and a locatable signal from the surface. Each model is pre-configured for its utility type: correct color, correct warning language, correct RF frequency. No field customization. No margin for error.
Four models. One system.
Each TM-2000 Series model is pre-configured for its utility type — correct APWA color, warning language, and RF frequency.
