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.
