Specialty conduit has the capabilities to manufacture a variety of HDPE conduit for specialty applications. BDI tracer wire (or toneable) conduit provides a method of locating underground fiber optic cable using a single copper wire co-extruded onto the wall of the conduit. This provides a traceable corrosion resistant conductor. An alternative method of locating buried fiber optic cable is to use traceable pull tape, available pre-installed in any of our duct products.
