Owners Ultra Wire Split Ring is one of the toughest split rings out there, for the most serious saltwater fish. From large tuna, Giant Trevally, and even to your Cape Cod Canal or your 9″ Musky Mania Doc striper fisherman, these split rings just hold up. Each split ring is made of high quality stainless steel and nearly double the strength of the Owner Hyper Wire Split Rings. If you’re targeting big fish, these are certainly the way to go!
