The Mustad double Stainless Steel Jigging Ring is a dependable lynchpin between the leader and hook. No rough edges to damage or cut the line makes it perfect for making double or single assist hook rigs for jigging. Use it when fishing for lighter jigging for Tuna, Grouper, Amberjacks or Pollock, Cod or Haddock in the North Atlantic. The dual jigging rings are perfect for separating assist hook leader from the jig eye, providing less tangle and less chance of cutting. Stainless steel for excellent corrosion resistance.
