A similar design to the oval split ring, this is a smaller version that will fit through the guides on rods. The small size allows it to be wound through the rings and kept on the reel for quicker setting up or for anglers who use different lines and need a quick way to replace their spool and get fishing. Its small size and strength make it perfect for using on the end of your shock leader for attaching rigs or as a lead link when you want to streamline your rig further.
