Decided to check out Oakey's trap setup with a Duke 155. This is what I found..........
From top left.....clockwise.......Duke 110, Duke 155, Duke 160 and Duke 220.

The 155 is a 5 inch trap and is built of same materials and appears to be exact same spring as used on the 160. Only difference is size of opening. It is a nasty little trap. Could be the spring arms are a bit long as the spring loop ends want to slide past the corners to the rivets......and don't want to go back. But doable with trap setters.
I imagine this is the trigger setup Oakey described. As shown, trigger clip and wires bent away from trap. Trigger wires are pointing in direction of travel so head will be perfect position for a neck strike. Oakey mentioned triggers wires bent "inward" and straight back.......so it could be he has it reversed from what I show. Trigger clip on first jaw coon encounters. Dog in back. The difference means about 2 inches of travel for coon's head before trap fires so it could matter.......a lot. Clarification would be helpful.
In this condition, triggers were good right out of the box. Trap stays set, but moment trigger wires start to move, the trap fires. As to 5 x 5 size, I once surprised a coon out by the chicken house and watched it slither thru a woven wire livestock fence like it was water. On the main trail they use to get to my barn, they go thru a livestock panel. The hole they use is no bigger than this 5 x 5 trap. Have no doubt if there is something they want on the other side, they will poke their head in there.
And being a 5 x 5, they should be legal for land use in MO. Cubbies and trail sets.
