Lance Camper Parts

It's not a Lance part. Lance buys from any number of manufacturers and installs them on their product. As you can see, it was made in Taiwan. Do a search for whatever that latch does and hit images.
"latch for Lance camper to hold access door up" or something like that. That's what I suggest to dear wife. I said suggest........
