yes, we put ours at the bottom of the sloped bit.
I don't quite understand this ( derr), surely you then need to put out leads & power packs?
Sockets? Do you mean with an adaptor or some new thing I don't know about?!
We have fitted 4mm sockets to all our rayboxes, as per an idea on here in top tips...
Our ray boxes have little battery boxes on the end. It saves using power pks. and no cables to damage.
