I have not used the Du-bro version, but the Sullivan came with a threaded rod. Does the Du-bro have one of these? It should be a small threaded rod with a hole in one end for the wire.

If not, go to the hobby store and get a couple of 2-56 eye screws. Use these on one end and that will allow you to adjust the tension since you can screw them into the clevises. Remember to put a locking nut on them also.

Good luck!
