Quoted:
Do you wanna put your money where your mouth is, or was this just a drive by rude post? The trap is built stoutly, and the trap, and it's mechanisms are an age old proven design.
I apologize if you took my comments as smartassed, rude, or insulting, as I did not intend them that way.
BUT, a large boar coon can destroy heavier box traps than that.
I've had them chew wooden traps to pieces, and bust up heavier gauge wire ones pretty badly.
Having the wire on the outside of the structure will enable them to pop it off the frame.
Continuous,single piece of wire (one seam) on the inside of the frame would be much stronger, preferably 1"X1" or 1"X2" heavy gauge/welded wire, and better protect the wooden frame.
A lot depends on the specific critter.
Some will just sit there, and others will dismantle the trap, then want a piece of you.
Also, stake the trap down, or otehrwise brace it, or they can roll it,and escape easier.
Again,sorry if I came across wrong.
Good luck, and I hope you catch him!
