What’s the best way to start stringing a Backcountry fence?

You’ve clipped the 3 blue insulators to each pole with the bottom clip 8” to 12” from the ground. The other two should be evenly spaced with the top one at the very top.

Take the yellow ring terminal that is already crimped onto the polywire, and hook it onto the little upright arm of the bottom clip as per set up instructions in the manual.

Then swing the line to the left underneath the clip. In this position, under tension, the ring terminal is less likely to slip off as you move.

String your fence counterclockwise, keeping some tension on the line slightly upward as you go.
