Spro Ball Bearing Swivel Coast Lock with 2 Welded Rings-Pack of 6
This swivel is an excellent swivel to use when trolling. "I connect all my spreader bars, splash bars, zuckers, jets and cedar plugs with this swivel and have had no fouling or twisting problems even at speeds of 10 knots." They are also strong enough to hold up to tuna in excess of 150 lbs.
