The Mustad Demon Link Stainless Steel Ball Bearing Swivels are a heavy-duty solution for angler looking to mitigate any line twist in their tackle. Its stainless-steel construction resists corrosion, rust, and other issues that would normally result in failures in lesser grade options. At either end of the swivel itself, welded solid rings allow for easy attachment of line and terminal tackle, eliminating any pinch points.
