Im not sure if the SO box warranty covers these so here ya go, today we took all the sliding plastic latches off our KRL series box. the things that you slide to the left in order to open the drawer. I know these break if the drawer gets slammed on them. so if anybody needs one just pay a few bucks for shipping. let me know what sizes you need. Pretty sure they wont work on your box unless it came with them from the factory. Il check how much shipping is if a lot of people want them.
