Waterproof Outdoor External Junction Box Cable Connector 2 Pin.
This is the tenth time that I buy such kind of junction. It is very useful on insulating wires on the garden. Firstly, I have some troubles with the incoming wires diameters, not providing a good water sealing. I have discovered that the incoming rubber tube may be easily changed for other ones, providing a very good sealing. I have tried several ones, but this kind is the best one.
