The Klein Tools VDV500-051 TONEcube Tone Generator is a compact 9V-powered analog toner for tracing wire paths in coax and twisted-pair cable systems. It supports five selectable tone cadences with continuity testing via alligator clips and modular RJ12 plugs. Auto power-off preserves battery life, with 120 active hours and 4-year standby on a single 9V cell. Heavy-duty leads withstand frequent field use. Now discontinued; no longer in production. Backed by a 1-year limited warranty.
Is the VDV500-051 TONEcube still available?
The VDV500-051 has been discontinued. The VDV500-063 Toner-PRO is the current tone generator, offering 5 distinct cadences, AAA battery operation (vs. 9V), and broader cable connector compatibility including RJ45.
What replaces the VDV500-051?
The VDV500-063 Toner-PRO is the standalone replacement. For a complete generator-and-probe set, the VDV500-820 bundles the VDV500-063 with the Probe-PRO (VDV500-123).
Can the VDV500-051 still be used with current Klein probes?
Yes — the 9V analog tones from the VDV500-051 are compatible with current Klein probes including the VDV500-123 and VDV500-223. However, the 9V battery requirement and limited connector support make the VDV500-063 a practical upgrade.
