The RK419WALVO 4U 19-inch Steel Side Mount Rack is a Wall Mountable 4U solid steel rack, providing a robust solution for mounting your telecom, network or server equipment. This server rack can be mounted in a server room, office, or above a doorway in rooms lacking the floor space for a full-size rack, expanding your workspace & keeping your equipment easily accessible. The rack is constructed to EIA-RS310 standards & allows equipment to be mounted horizontally, leaving the front & back open for easy access to LEDs, configuration buttons & cabling. Alternatively, with the included bottom cover plate, your equipment can be mounted vertically; non-rackmount equipment can be installed using the rack as a wall case. The bracket mounting holes (used to mount to a wall or the desk underside) are positioned at exactly 16-inches apart, matching standard construction stud measurements for easy installation.
