The StarTech 3ft (1m) Vertical Cable Management Duct with Cover is a 0U rack accessory used to organize and route networking cables vertically within a server rack. It features a finger-duct design with a removable cover to conceal cables, improving the rack's appearance and accessibility. This organization helps promote passive cooling by improving airflow and reduces strain on equipment ports, which prevents damage. The panel is compatible with most standard 19-inch racks that are 20U or larger and offers versatile, often tool-less, installation options.
