QC Hook Flexi-Ring Swivels feature a reinforced open crook for quick and easy attachment of hooks on Ronnie style rigs. • The wire gauge and diameter of the crook has been specified for strength and ease of use. • Secure the hook in position using a Covert Tungsten QC Hook Swivel Bead or suitable tubing/shrink tubing. • Flexi-Ring design allows free rotation and movement of hooks and reduces tangles with hooklinks. • Anti-Glare black finish reduces visibility under water.
