Twistlock ® JigRigâ„¢ combines two unique Owner concepts. The hook is "free-floating" from the weight to allow maximum bait movement. With the weight leading the way, the compact profile of the rig allows for longer, and more accurate casts. Adding to the many attributes of the JigRigâ„¢ is Owner's unique Centering-Pin Spring (CPS - US Patent # 7,841,127). With the CPS attached to the eye of the JigRigâ„¢ hook, baits can be "permanently" secured by inserting the pin in the center of the nose of a soft plastic, which can then be screwed onto the Twistlock ® coil spring so that any bait will rig perfectly every time! The specially designed hook for this rig features a cross eye (to accommodate the CPS) with a 30 ° eye bend, a 3X-Strong forged shank, Super Needle Point, and a black chrome finish. 2 per pack.
