I'm in a Class A with 2 folding/accordion doors that no longer have the small plastic or rubber nub in the wall that they'd push into to hold them shut, and for the life of me I can't seem to find the part as I've scoured RV door hardware sites. I've tried various hacks to keep the doors shut and so far nothing really works reliably while allowing the doors to be opened and closed easily from both sides. Anyone know what I'm referring to and where I might be able to locate a couple of them? I have a picture of what I think is the same part for my shower door, as well as one of the door itself for reference.
