Data Cabinet/Rack Size Guide
Confused by 'U' (Rack Units) when looking at data cabinets? Use the following table to work out the height of a cabinet in inches, centimetres or feet based on the U height.
Please note that the height of the cabinet/rack stated here is the useable internal 'working' height of the cabinet/rack. You must take into account jacking feet or castors for the total height of a cabinet when measuring up.
If in doubt, please contact us.
