I've got one of the Toughsystem 2-drawer units. Top drawer latches just fine. Bottom drawer will (mostly) close, but won't latch. If I turn it up on its back, the drawer WILL close and latch with no problem, which makes me think there's some binding issue along the bottom edge. Issue persists whether drawer is empty or loaded. Can't see how to remove the drawer to see if there's something in there that's causing the bind. Anyone know of a fix?
