DELL 770-BBIF rack accessory

- Provides tool-less support for 4-post racks - Support a wider variety of racks The ReadyRailsâ„¢ static rail kit from Dellâ„¢ provides tool-less support for 4-post racks with square or unthreaded round mounting holes including all generations of Dell racks. The static rails support a wider variety of racks than the sliding rails but do not support serviceability in the rack and are thus not compatible with the CMA.
