This anchor system allows you to firmly attach the winches on a tree or a post. The winch can thereof 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 to get the Winch support plate (PCA-1268) or Vertical pull winch support (PCA-1264), both sold separately. The four rubber pads will prevent the system to slide on a pole and will protect the bark of your trees!
