The Heavy Duty Rack Cabinets can be configured with and without side panels or even just one with the choice of side, to map exactly to your requirements. Choose both side panels if the rack cabinet will be placed standalone or you want to isolate airflow, choose one side panel with left or right placement for racks that are at the end of a rack row and leave them off for racks that are placed inside the row.
