This anchor system allows you to firmly attach the winches on a tree or a post. The winch can be installed at a more comfortable height and the pivoting support aligns the winch automatically with the load. This makes it easier for working from one point for extended periods of time. It is also used for vertical pulling of wires or lifting. To use it, you will need the winch support plate (PCA-1268) or vertical pull winch support (PCA-1264) sold separately.
