I am looking for a floor receptacle that allows the plug to be completely below floor level. I have a floor outlet currently that is under a rug. It could be used except the plug cord plug is at the same level as the floor. I have seen some that appear that the plug is below floor level so that only the cord would be felt under the rug. Lew Electrics has them but it is impossible on their website to determine which one exactly does that. Can anyone help with any suggestions from Lew or anyone else?

Thanks!
