Floor Mounting Options Use one of the following types of mounting hardware between the bay and the
floor:
• Rittal Base/Plinth System on page 41

All mounting options use the mounting holes that are located at the corners of
the base of the bay. All four mounting holes must be used to secure the bay
properly. Remove the debris plug when using mounting hardware that must
pass through the mounting hole.
