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

Take the ring terminal (yellow) that is already crimped onto the polywire, and hook it onto the little upright arm of the insulator clip (blue) on the fence pole. This clip should be the one lowest to the ground 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.
