The Strike King Tour Grade Tube Jig Heads feature a classic design that fits all varieties of tubes and other hollow bodied baits for the perfect presentation. The head of the jig easily fits inside the hollow cavity of tube baits for a streamlined natural profile. Simply insert the jig into the hollow tube head first and push forward until the eye of the jig pokes through the plastic. These jigs are built around a light-wire black nickel round-bend Gamakatsu hook. The 60 degree horizontal line tie helps create the erratic fall action that is key for catching fish on tubes.
