Maine Style Coil Spring Trap Setters are specifically made for setting coil spring traps from #1.65 and above. There is a slot cut in each of the metal plates on the end of the setter handles. The Maine Style setters are used as a pair, one fitting on each trap lever on opposing sides of the trap. Center each trap lever within the slot and then draw the Maine setter handles together. This depresses each lever to a point where the jaws fall open, allowing you to set the trap. You can also hold the set trap in one hand utilizing the setter handles.
