The Owner CPS Centering Pin Spring allows you to secure soft plastics by first inserting the pin into the nose of the bait and then screwing the metal spring into the bait. The pin guides the metal spring onto the bait which allows the bait to sit on the hook in a more natural way. Smaller/larger CPS springs can be used on Owner CPS spring hooks to better match bait profiles or can be utilized in other rigging techniques.
