Bulldog Winch 1/2in Rope Shackle 38K lb WLL. Installation is as easy as snapping the shackle wrapping the rope around a fixed point then pulling the rope until it will give. A shackle is required to secure the rope and is a device to prevent the rope from moving under tension. For proper installation make sure you are following the manufacturer's recommendations. Our 5/8in Shackle should be used for every rope you own. Having a large inventory of these critical parts makes sense for every serious off-roader. A shackle is only as good as the materials and workmanship that goes into it. Make sure you have the right shackles for the right jobs.
