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 and keeping your equipment easily accessible. The rack is constructed to EIA-RS310 standards and allows equipment to be mounted horizontally, leaving the front and back open for easy access to LEDs, configuration buttons and 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.
