I have searched the internet high and low and don't seem to be able to find Flush mounted wall Electrical outlets with more than 3 plug outlets.
I know I could mount two together etc but I don't want to go down that route as I need 12 sockets in the AV cupboard. Has anyone found any flush wall mounted sockets more than 3? I heard there was a vertical system somewhere but couldn't find it.
Any help would be greatly appreciated.
