The Pro-Line TS-SHUNT (Millennium part 527541) is a replacement shunt for cathodic protection test station terminals mounted in marker posts and pedestals. Installed across the terminal posts, it bonds the test leads so the pipeline or casing circuit stays electrically continuous, then lifts out when a technician needs to read potentials or current with a meter. Keeping spares on the truck avoids leaving a station open or improperly bonded after a survey. Stocked at Millennium with Pro-Line RhinoDome test stations and marker post hardware.
