Built with narrow and wide fingers, the 2U Slotted Routing Cable Manager is a cross between the 2U Finger Duct Cable Manager, the D-Ring Cable Manager, and the Cable Routing Blanks. The narrow fingers allow for separation when routing cables between switches and patch panels, while the wide fingers help to retain cables during and after installation. For added protection and storage, a cover is also included to enclose the cables and create a clean look for your rack. Flanged fingers are an extra feature to help when routing cables, and to help contain cables should the cover be lost or temporarily removed.Rear cut outs allow cables to pass through the back of the unit - a great feature when mounting two units back to back. If mounting two units back to back, the 2U Finger Duct Cable Manager is another option for the front installation. Messy and unmanaged cables are no longer an issue with the 2U Slotted Routing Cable Manager.
