This is a press fit lid catch for Milwaukee packout number 48-22-8436. It is supposed to help keep the lid closed to prevent accidental spills if you forget to use the latches on the box. These press fit in the opening right behind the latches and keep the lid fairly well closed by just gently pushing the lid closed. This still allows the lid to be held with the original latches as well when these are installed, but it is little more difficult to open the lid with these in as it eneds to be a tight fit to catch the lid.
