I do know that some stupid things we do is a code requirement.
We have an access door that we attach using barrel latches. Door comes off all the time, hard to get back on. When I asked engineering about it, they said if we hinge a door in certain areas it MUST be for storage only. Access panels must be screwed on, otherwise a consumer assumes it is for storage and puts things in there when they shouldn't be.
