The network rack is 12 in. (30.4 cm) deep, so it's perfect for smaller spaces. It's easy to assemble and features mounting holes that are spaced 16 in. apart, making it suitable for mounting on almost any wall, based on common wall-frame stud spacing. The wall-mount rack comes in a flat-pack which makes it easy to transport and reduces shipping costs. You can mount the open-frame rack where space is limited, such as on a server room wall, office, or above a doorway, to expand your workspace and ensure your equipment is easy to access. By having an open frame the server rack provides passive cooling to equipment. Additionally, the open frame provides easy access and configurability to your equipment, allowing you to maximize productivity. The RK12WALLO is backed by a StarTech.com 5-year warranty and free lifetime technical support.
