Alrighty making a lil 12x16x36 ring lock and I think it's pretty well set up but wanted to see if y'all could think of something before I put the wire on it .
It's 1/4 hot roll frame , rod door , trigger bar is 1/4, chain is #2 import, pan is ... I'm not 100% sure on the gauge but it's kinda thick , goes off at like 2lbs , pan is a little closer to the door then normal rings are welded together via a rod so they can be raised easier. Was considering a bait door but have seen those go wrong with coon , so , anything else I should do or add before I put the wire on ?

Cool idea with the rings welded together like that, never saw that before, does it ever get cocked and hung up?

Otherwise I'd say you're good to go...

I like the idea of pan being a bit forward vs. way in the back. I use William's cage traps; I like their pan placement.

I like your idea of a bait door and would say if you do add one might suggest putting it on the top at the back of trap but far enough forward can hang bait behind it

Looks good to me.
I don't think the bait doors are all that necessary.
I put the bait under the cage any way.

Wire away

Coon will end up lifting up on that bar thus lifting both rings and away he goes.

Uhhhh...no. Not happening

But what might happen is if something gets the cage to roll, the rings can fall which will allow the door to open. I would say you should put something across it to keep it from rolling. Just a iron rod through the wire a couple of inches up..serves 2 purposes..no roll and the coon will step over that onto the trigger.
