StarTech.com 3U Unvrsl Rack Rails

These 3U server-rack rails let you mount non-rackmount equipment such as desktop servers, networking equipment or KVM switches, into your 19" server rack without sacrificing an additional 1U of rack space, like you would with a traditional shelf. The rack rails are also a great solution for mounting equipment with damaged rails or discontinued OEM equipment such as Dell™, IBM®, HP® or Apple servers that no longer have rack rails available.
