The Megger 1006-449 DTP1-C Duplex Connect Handspike features sprung twisting tips fitted with a connector socket for easy connection to any connect test lead.

As the probe is pressed onto the test piece, the tips compress and twist at the same time providing 2.4 kg of spring force. Probe tips are hardened and tempered before four equal-spaced flats are ground to provide a square shape tip, making these probes ideal for cutting through surface coatings or corrosion on test piece for a good contact.

To increase reliability, the probes' internal electrical connections are assisted by using an innovative volute spring, eliminating the need for a separate current carrying brad.
