Simply a better solution for keeping stock on a highline! The In-Line Swivel ensures that a lead rope will not become twisted or unravelled while tied. Easy to use: when line is loosened, the In-Line Swivel may be easily slid to the desired location. Once the line is tightened, the In-Line Swivel will not move, keeping stock animals from becoming entangled with each other. Stainless steel construction will endure years of use.
