Now you can switch out your dredges quickly and confidently without fear of losing gear. Only AFW offers true 500 lb and 1,000 lb test rated Dredge Swivels. We beefed up the thickness of the stainless steel corkscrew snaps for added strength and security, and we paired the snaps to our proven dual-rotation stainless steel ball bearing swivels with welded rings. Our snaps and our swivels exceed our strength ratings, not just our swivels like other versions sold on the market. The stainless steel ball bearing swivel in the dredge swivel is patented under D549,750 S.
