Let me try again.
Those catch latches I linked are the ones used on my blower door. I have had one fail in 7 years. The door has never opened while underway. They are mounted vertically with 4-40 stainless screws and nuts. Riveting through the plastic doesn’t work very well.
On my first coach, the finger operated latches failed because the spring rusted and fell out. I made new springs for those by using appropriate diameter music wire, bending it to shape, heating dark red, and quenching in oil. If you want to go that route, look up making springs on U tube, It’s been 12 years ago, so I don’t remember the diameter of the wire.
