Dell Customer Kit - Rack rail dual tray - 4-post - 1U - for Networking S4112F-ON, S4112T-ON, PowerSwitch S4112F-ON, S4112T-ON

The static rail kit for 1U systems provides tool-less support for 2/4-post racks with square or unthreaded round mounting holes including all generations of Dell racks. It also supports tooled mounting in 2/4-post threaded racks and 2-post (Telco) racks for added versatility. 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.
