No trigger wire in the animals face. Large animals like raccoon, fisher, and bobcat spring trap with chest or chin. Small animals like mink, marten, and weasel step right on the pan. Less refusals on large animals. Less misses with small animals. Simply slide the trigger wire through the pre-drilled holes in the hardwood pan, bend the trigger wire over to hold the pan on and you’re ready to set your trap. Easily removed if you want to use original trigger at a set.
