SKB's 3RS Shock Rack cases are tougher, lighter, stronger and better than any other rack case out there in the market. The 3RS series cases are identical to the 3RR series only with a static mounted shock rack instead of a removable rack. These cases are also featured-packed for ease of use, with convenient integrated wheels (24” and 30” models only), lid hangers, couplings straps, and more. All 3RS cases are independently tested and MILSTD 810-G certified. This means you can use our 3RS racks in the most extreme environments and conditions while your sensitive equipment will keep working and stays protected. And we are so convinced of the quality that we back it up with a lifetime warranty! These 24” deep rack models are suitable for IT equipment such as routers, switches, storage and communication devices. Typical applications are in military, security, and broadcast, where maximum protection is needed!
