This 12U portable server rack delivers secure, mobile, and easily adjustable equipment mounting for data-centers, labs, and office environments. Constructed from heavy-gauge steel with a durable black powder-coat finish, its self-squaring design and ball-bearing casters let you roll standard 19″ rack-mount devices in and out with minimal effort. The adjustable mounting depth (19″–29″) accommodates a wide range of switches, servers, and UPS modules, while optional front/rear covers (with padlock provision) protect against tampering and dust. Louvered side panels improve airflow, and labeled U-markings make device installation intuitive.
