In some photos I see locks on the latch, or just a hook and eye... what all do you guys use for latches, and for anyone with a lock, is that to keep out thieves or predators or both? I rigged a U-bolt through two eye screws temporarily on my new side door, drop the ubolt in each eye, screw the bolts on about halyway up... coon won't have the patience or understanding to twist both bolts for that long. The front latch is a two-handed job because of it's age and crooked placement. LOL You have to lift the the vertical hook while pushing the parallel bar forward, otherwise it'll snag on it's self. It's a gate latch really, but more secure than a lot of door latches I saw, which is needed because it's low to the ground and if a coon wanted to, it could sit down on it's hunches and play with it. But with the two-hand required motion and the knee to the center of the door, combined with the strength for all 3 motions... a coon isn't figuring it out. Worked with what I had. Just a hook and eye high up on the run gate, since it's for day-time use only. Put it higher than dog nose level.
