Standard size 8 swivel with an extra ring attached. The bottom line can be tied to this, but this ring can also serve as a "blockade" to prevent the swivel from clicking into a lead clip or insert.
This way you can fish the assembly as a “run system”. This Ring Swivel has a Dull Finish. Ring swivels are ideal for anglers who prefer not to tie a loop knot. Tie directly to the ring and the rig remains flexible.
