EZ-Upgrade Voltage Test Station Kit with horizontal mount includes R-3MT (Safe Test Point), Protective Housing, and Magnetic Installation Template (Unassembled Kit). You can now easily upgrade your standalone Voltage Indicator (R-3W Series) or Safe-Test Point (R-3MT Series) into an all-in-one Voltage Test Station (VTS). GracePESD Voltage Test Station (VTS) provides LED indication when voltage is present and has been making the absence of voltage testing safer and more productive for years.
