The TIC 410A hot stick attachment physically and electrically extends the reach of the TIC 300 PRO high voltage detector for checking transmission lines, power distribution equipment, down power lines, fuses and load break connectors. The TIC 410A universal adapter extends the voltage limit on the TIC 300 Pro from 1500 AC to 122000 VAC (122 kV) and adjusts from 33 to 57 in. Just screw it onto the universal adapter on the TIC 300 PRO high voltage probe - no other tools are required.
