You probably don't want to hear this but i've just binned a decent one of those :cry: But the good news is that it is relatively easy to change the backbox to suit one of the double socket sized CCUs. It is only the height that is different, so change the backbox and fill the gap top or bottom...
That really is one of my pet hates. Did a db change recently where every RF circuit had been done like this, and up to three lighting cicuits at a time in a bunch with cpcs twisted in one earth sleeve.
