I've got a bunch of TV and audio leads to run through a wall with face plates and connectors either side.  The boxes I have have have four punch outs but it would be so much easier if the whole back of the box was removed. Before I get the hacksaw out is there such a thing a a back box without a back?
 

Something like that will be perfect. I'll drop in the local electrical supplies place and see if they have any.

Thanks!

Try looking into the q-max sheet metal punches, you drill an 8mm hole and then insert the tool on either side and tighten up forcing the punch through the plate leaving you with a perfect burr free hole.

They come in loads of different sizes.

Those punches worked out ok. This is the resulting faceplate...

   

Top row has four HDMI sockets, bottom row has two Speakon sockets, a Network port, an F series/aerial and a 3mm jack for an IR extender.

The HDMI and network connectors are "through" type (eg they have a matching socket on the back) so premade cables can be used both sides.

Hard part was getting everything lined up. Didn't quite manage a perfect job despite printing the layout onto a sticky label. One problem with the punch is they only have small flats on the "nut" part. It tended to pull out of the vice while trying to put max effort into turning the allen key. Had no problems punching holes close together and much easier than drilling and filing out.

Edited:

Yes it's to match existing plates from

Unfortunately rather expensive.
