The controller is rather large, and the adaptor that goes with it is:-

(although I have been using a slimmer one).
With the original adaptor, the whole lot sticks out from the wall by 150 mm and is very wobbly.
If I could find a French socket, that would be down to 80 mm and the body of the reflow controller would rest on the wall. The whole thing would be much more secure.
Well I bought one of those sockets from RS. I've fitted it in a dual wall box with a fuse switch. Here are the photos. It's much more secure than when it is in the adaptor it came with. The last photo shows what that monstrosity looked like.
I would have prefered a French socket, instead of the German type as I think that the reverse earth pin is better, but the front of the controller has a German type anyhow.
