The frame of the cabinet has metal that is so thin the bottom drawer comes off its runners if top two drawers are filled with hanging file folders. Sides must flex causing the problem. Not recommended for office use.
Do not waste your money on this filing cabinet. within a few days the drawers no longer aligned and stayed on track now only 2 of the 3 drawers lock and I JUST purchased this in April and do not have it overloaded with stuff.
