I asked Jim Palmer that same question in 2013 and he replied:
The cabinet latches (we have used several styles as they are rarely the same each time we order) are a standard rv/motor home item , you can likely
match replacements at the local rv parts dealers (take one along to match mounting holes) for less than shipping cost.
Justin, you might also find a match on Amazon if you are not conveniently located near an RV parts store. That’s what we ended up doing and we have not had any problems at all with the new latches. Hope this helps!
