The security locking bars allow you the option of adding a padlock to your Multi-Media Cabinets. When you add security locking bars you make the cabinet dual access as well. When the key lock (standard on all cabinets) and pad lock are engaged it requires TWO separate keys to open your cabinet. Finish matched to the cabinet. (Padlock not included) Note: Locking Bars reduce useable cabinet space by 1.0
