Krok”Billfisher” stainless steel ball bearing swivels and snap swivels feature dual rotation which allows the swivels to rotate at both ends, producing less friction and eliminating line twist. The patented one piece body and all stainless steel construction make Krok swivels some of the strongest ball bearing swivels available, enabling the angler to use smaller swivels without sacrificing strength. Krok swivels feature a nickel black finish and double welded rings which are sure to please inshore and offshore anglers alike. The swivel bodies are constructed with a machine-milled knurled finish that allows for maximum gripability.
