ABSTRACT:
A cylindrical duct of plastic material is coextruded with a longitudinal wire located between the duct inner and outer surfaces, and with a stripe of a different color plastic material than the duct overlying the wire. The stripe is of a softer plastic material than the duct plastic material to facilitate cutting of same to expose the wire, but is compatible with the duct plastic material so as to crosslink therewith.
