This kit includes the necessary hardware to add to your provided ½” fiberglass rod in order to make drowning rods. The lock is designed to slide over the top end, creating a tool-less trap connection to the rod, making setting super-fast while providing versatility to switch from rods to wire, etc. as the lock is always attached to your trap. Additionally, this keeps your truck organized and tangle free as traps are easily removed from the rods. To complete the “system” you will need a ½” fiberglass rod, 3/8” T-bar, J-hook or quick link and your favorite trap.
