The Mad Katz 3-Way Crane Swivel is highly effective for bottom-bouncing rigs, eliminating line twists and tangles that can occur during fishing, especially when the bait starts twirling or a hooked fish tries to get free. The crane swivel is similar to the barrel swivel but performs better under tension from a heavy load than a traditional 3-way swivel. The 3-Way Crane Swivel is best used with heavy fishing lines for catching giant catfish and other behemoths. Each pack contains 25 heavy-duty 3-Way Crane Swivels in 3/0 size, ensuring you have plenty to last and can withstand heavy weights and trophy-caliber fish!
