There are a lot of plug receptacle options at Parts Express . com I'd check with them, what you are trying to do is pretty straight forward.
Installing new wires in room with hardwood floors
I want to feed a new cable tv wire and Ethernet wire into room with a hardwood floor (going through wall more difficult and thru floors may be less visible). Wires being fed up thru basement ceiling access. Need a plug-in style outlet for cable and Ethernet jack access at floor level. Interested in ideas on how to get these wires into a room.
