Martindale VIPDLOK138-S Lock Out Kit
The Martindale VIPDLOK138-S Lock Out Kit helps electricians carry out safe isolation with confidence. It combines a professional voltage indicator, a proving device, and a complete lockout set in one package. As a result, users can verify circuit status and apply lockout procedures using equipment designed for electrical safety work.
Designed for industrial, commercial, and domestic environments, the kit supports safe working practices before maintenance begins. The supplied VI13800 voltage indicator operates without batteries and tests AC/DC voltages from 50V to 600V. In addition, the PD440S proving device allows users to check tester operation before and after use.
Reliable Voltage Verification
Clear LED indication provides fast voltage and polarity confirmation during testing. The Martindale VIPDLOK138-S Lock Out Kit offers voltage threshold indication at 50V, 100V, 200V, and 400V AC/DC RMS. Furthermore, the double-insulated cable design includes a contrasting inner core that helps reveal damage during inspection.
Fast response times and low test current help improve testing efficiency on site. The voltage indicator is rated to CAT IV 600V and carries an IP54 rating for protection against dust and splashing water. Therefore, it is suitable for demanding working conditions where dependable performance is essential.
Complete Lockout Solution
Alongside voltage testing equipment, the Martindale VIPDLOK138-S Lock Out Kit includes a comprehensive lockout package. Users receive multiple MCB locking devices, warning tags, a hasp, and identification accessories. Everything is supplied in durable soft carry cases for convenient transport and storage.
Two different set types are available to suit different requirements. The VIPDLOK138-S combines the VI13800 voltage indicator, PD440S proving device, TC71 carry case, and 12-piece lockout kit. For users needing an expanded solution, the VIPDLOKPRO138-S adds the LOKKITPRO 17-piece lockout kit while retaining the same voltage testing equipment and proving device.
