Need Backplate for 7.1 Wall Plate

[NickOrangeTVR]

In middle of a home cinema build and I got a nice 7.1 Wall plate from amazon - but I cannot find out what kind of backplate is needed for it to go into the wall.

Anyone got any ideas?

This is the item on Amazon - http://www.amazon.co.uk/gp/product/B004C4WF1C/ref=...

That looks to be Yankee sized. Triple socket for them. Not sure what it'd bodge into for us.

I am taking a wild punt that this might be the jobbie:-

Going off the description of :-

"Requires low-voltage mounting bracket for proper installation"
