The Automatic Trucker's Hitch is just what the name implies. It is a Trucker's Hitch that automatically locks off the tension you apply to it. It also allow you to tighten down your load quite a bit tighter because it utilizes an additional wrap on the the working end, thereby increasing your leverage. It holds best when using a smaller diameter rope or cordage, but can be tied effectively with a variety of different types and sizes of rope.
