How do I find the fire rating certification label on a fireproof filing cabinet?

The UL certification label on a fireproof filing cabinet is typically located inside the top drawer or on the interior side wall of the cabinet. It shows the UL logo, the Class rating (Class 350, 350 1-Hour, 350 2-Hour, Class 150, Class 125), and the certification number. If you're purchasing a used cabinet and want to verify its rating, look for this label inside the drawer. If the label is missing or illegible, the fire rating cannot be verified. For new purchases from FindOfficeFurniture.com, UL certification is confirmed — call 888-719-4960 to verify specific models' ratings before purchasing.
