Galvanised conduit male coupler [PLU60646]
Industrial Galvanised Conduit male coupler.
This is a male coupler for the 20mm conduit range.
This allows you to convert a female thread into a male thread, as some accessories like the galvanised dome cover has a female thread and you want to add a battern holder onto it that also has a female thread.
You will need this male thread to join the 2 together.
