Our Earth connection plugs have two connection points, and the grounding rod has one. This splitter can be used if you want to use more grounding products with the same plug or rod.
It can also be used on the end of an extension cord to provide extra connection points.
Please note: If used with a UK connection plug, the splitter will cover the other hole in the plug. So a single splitter will still only allow 2 connections in total. Additional splitters may be added to allow more connections.
