ABSTRACT:
An insert bridges a junction box to provide a continuous path between consecutive pipes of an electrical wiring guideway. The insert includes a generally tubular body having a first end and a second end. The insert has a length that is sized to bridge a gap across the junction box and a diameter that is sized for sliding into a pipe of the electrical wiring guideway. A first flange surrounds the generally tubular body and is spaced from the first end thereof. A second flange surrounds the generally tubular body and is spaced from the second end thereof. The flanges abut opposing inner walls of the junction box to ensure that the insert is not lost into a pipe. A slit extends along the length of the insert to allow for removal of the insert once the electrical wiring has been laid.
