This "TENS/2mm to 4mm adapter" is a replacement for both adapters: the TENS to 4mm adapter and the 2mm to 4mm adapter. The advantage: one less adapter that you have to hold on to in case of doubt, because this combination adapter takes on the task of both at the same time. The item is delivered as a pair in a plastic pack.

The two specially shaped adapters allow you to connect either a device with a TENS connection or a 2mm connection to any E-Stim Systems electrode or other accessory with a 4mm socket. The adapter is always sold in pairs.

The adapter is especially useful if you have a non-standard or imported TENS device and want to use it with the E-Stim Systems electrodes (or other accessories), as most of these devices use the TENS connector.
