Hey all, I just picked up a 1998 Northwood 21c travel trailer and the electrical panel is missing that small plastic latch you have to twist to get it to stay in place. I've googled a bit and can't find anything close to what I'm looking for so I think I must have the wrong name... They are also quite common on the outside of this trailer for all of the appliance covers. They are maybe a half inch by quarter inch, and it's just a plastic screw-type device that only goes a quarter turn to latch and unlatch. Thanks in advance!
