This system was designed for vertical pulling. The 50,8 mm (2') square tubing fits on different Portable Winch parts: Winch anchor system for trees and poles (PCA-1263), Adaptor for Heck-Pack (PCA-1265) or Square Tubes (PCA-1267 and PCA-1501) when using a vehicle as an anchor point. It is designed so the rope goes through the swivel pulley and then straight up. It offers a solid support and is ideal for pulling electrical cables through conduits or lifting equipment. It can also be used for pulling when used with the pivoting anchor PCA-1332.
