Dell Networking Rack Rail Dual Tray, 1U, 4-post rack only for S4112

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. This product has been tested and validated on Dell systems. It is supported by Dell Technical Support when used with a Dell system.
