Abstract
Disclosed is a rail-type fence using electricity which includes a plurality of support posts between which are extended continuous electrical wires. The electrical wire is enclosed within and supports a conductive tubular rail. The wire is held against the inner wall of the tubular rail by end plugs and splices. An alternate embodiment of the rail-type fence includes a plurality of electrified wires positioned within the outer surface of the walls of a nonconductive tubular rail. In this embodiment, a conductive end plug transfers electricity from the electrical wire within the tubular rail to the electrified wires embedded in the rail's walls.
