The ZeRAK™ is an aluminum double entry case designed and engineered to provide a minimum of 40G protection for sensitive electronic equipment. Based on the ZeRAK™'s weight, size and price, no other 19" aluminum rackmount case offers this level of protection. A smaller footprint and lighter weight delivers greater efficiency in transportation and usage. This case meets the rigors of environmental conditions including temperature ranges, altitude, rain, sleet, snow, sand, and dust.
