Ok, same filing cabinet, different issue.
We've changed the lock on the cabinet. The drawer with the lock, locks. The lower drawers don't lock when the top drawer is locked.
I don't see any obvious mechanism by which the lower drawers would be kept shut by the top one.
Can anyone suggest anything I can check, or point me to some online technical reference to these Quill fire-resistant, locking filing cabinets?
Thanks in advance.
