I have 2 others that are identical, is it possible that these were pre-spring and lock?

Take and bend the tabs out so when the door closes the rods behind the tabs . Thats how mine's set up .

That trap pictured is not a Havahart , looks like a Little giant or a chinese havahart knock off. The newer pro model Havaharts with the sheet metal door have gussets on the door to reinforce them , the older pro models had a wire mesh door and were a very good trap . Cant see all the trap in the pic , but it looks like parts are missing from the door.

I took the rod off and wound the springs tighter and tweaked it again. Hopefully she'll last a spell, if not I'll make a cone or something out of it. Thanks everyone for your help!

9 gauge wire on top of the cage with a small bend into the wire where the lock bar can get under the tip and the keep it from coming back!

After repairing the trap yesterday I felt confident to set it, if I didn't I wouldn't have. There's nothing worse than worrying about a trap that may or may not work. Anywho, I set it and it did it's job. Thanks again for all your help guys.

Good Deal

From the first pic I thought it just like mine, todays pic shows it is not. They made more than a couple versions. This happens a lot here, comparing "names" of traps.

Thanks to the discussion I think I can improve mine above rabbit trap status.

I'm gonna look for some stronger springs that will fit. It made a huge difference when I wound them tighter, it made the bar to not want to leave the tabs.

I'd put some more cage clips or hog rings on that back panel. The ones there scare me as ive lost a few animals to those.
