A continuous, non-metallic conduit for conductors, such as electrical wiring and/or fiber optic cable. The continuous conduit being formed from at least one pair of first and second conduits having enlarged ends coupled together. The enlarged ends are belled or otherwise have a diameter greater than that of the straight run (non-belled) portions of the conduit. The enlarged ends of the conduit being coupled together by fusion or welding, and an internal bead or ridge being formed by the coupling process. The enlarged ends are dimensioned such that the internal bead or ridge formed at the junction between the two enlarged ends does not project radially inward to a position equal to or less than the diameter of the straight run portion of the conduits. The continuous conduit is configured to allow the conductor to be passed therethrough such that the conductor does not contact the internal bead or ridge.
