Abstract: A tool is provided to assist stringing fence wire during building of a fence. The tool comprises a hanger for suspending the tool from a secondary fence post, which is typically a metal T-post. An upright attaches to the hanger and provides a series of arms extending away from the fence post. The arms include an end structure that support fence wire against downward movement and against movement away from the fence post, all in an effort to minimize entangling of wire before it is tightened. After the fence wire is tightened, the tools are removed from the fence post and may be reused. Several different types of end structures are provided.
