This high-security 2U rack-mount cable management and cover kit is designed to install over standard 19" equipment racks or cabinets, takes up no additional rack spaces, includes a tie bar with multiple cable exits, and can be installed over already working equipment, including mid-mounts. It protects access to all sides of the equipment, yet provides adequate air flow for equipment fans and secure cable management, and can be used with NO/NC contact alarm sensors.
