How long is it?
Assuming it is made for cat, coyote, beaver, otter I think it is too short, 17 inches into the trap when they trigger it with a guillotine door I think they are likely to hold the door open with their back and back out.I know a theory has it that if an animal gets hit on the butt they will jump forward. Could be but 17 inches I think it will drop on the middle of their back. They need to be in a little further IMO.Could work if there is a lot of play in the trigger and they get past halfway before it springs.
My double door beaver, otter, cat traps are 40" long, never a problem. I make the shorties for beaver and otter at 32" ling. All those have the inward opening doors. Guillotine doors are a different matter though. I believe the trap would have to be longer with guillotine doors.2x4" actually, never had much of a problem holding smaller critters with it in other traps I'm not sure what size your possum are but I would think most would slip out of 4x4 mesh. Maybe that is a good thing>
