    Abstract: A door wire routing system for efficiently routing wiring from a door jam to a swinging door in a concealed and protective manner.

One of the guide members is installed within an opening within a doorjamb and the other guide member is installed within an opening within an inner edge of a door member. The wire is extended through the tubular member for providing electrical power and data communications to the door member.
