Save money by mounting all of your equipment in one rack With this adapter kit, you can customize your server rack to support different mounting depths, so you have the freedom to mount equipment of different depths in the same rack. It's a cost-saving, hassle-free way to consolidate your equipment into a single rack, so you have one server rack to manage instead of two. Cable management flexibility The depth adapter kit can also be used to help manage cables. You can mount equipment 4" in from the rails, to prevent cables from protruding from the rack. You can use the rail depth adapter to mount equipment that has high density cabling, such as patch panels, PDUs or network switches, to minimize the effects of cable strain and provide easier access to the cables. The RDA1U is backed by a 2-year warranty and free lifetime technical support. More from the Manufacturer...
