The open-face pulley is designed to pull trees perpendicular to a path when the traction comes from a vehicle. It is also useful for deviating trajectory and get around obstacles. In addition, when installed at height, it creates a pulling angle that allows the tip of the log to be slightly lifted and thus reduces friction on the ground.
Made of steel, it is shock-resistant and is generally used paired with the automatic release (PCA-1291). The sheave is smooth and without sharp edges: it will not damage synthetic lines. Its 4'' diameter provides excellent efficiency.
