If you tie your mainline or leader direct to the eye on the nose of your lure the tight knot will dampen the lures wiggle and affect its performance.  Split rings enable the user to get the best action from their lure.  Rigged onto the lures nose, split rings will allow most types of lure to swing more freely giving them a better action than when one ties the main line or leader directly to the ring, and can be used in conjunction with a clip or a loop knot.

Swimerz stainless steel split rings also make ideal replacements for split rings that may become damaged or can be used as a Stopper Ring when slide baiting or using running sinkers, for example.

Made from high tensile stainless steel, these split rings are extremely durable and are made for marine and fishing applications.
