Checked my silverware drawer out yesterday. Mine don't have the upper and lower screw adjustment, but is easily adjusted by physically moving the drawer slide part attached to the drawer and re-attaching the screws. My silverware drawer front was slightly warped from the factory. All the other drawers are OK, so that's why one side was not staying latched. Got it to latch on both sides now, so OK now. I can always swap drawers also later if this happens again. This drawer will be used about 20 times more often, so it needs to work good.
