RackSolutions' Metal Horizontal Cable Manager is perfect for organizing and securing cables within a server rack. When mounted between two patch panels, the finger duct design makes it easy to separate, route, and organize patch cables between each panel. Both options have a metal plate (180-4942), but one has a plastic duct (180-4943) which allows for more fingers, or more room to route cables. The metal version offers greater strength and a few less fingers. Each cable manager comes with a removable plastic cover that easily slides on and off, making it easy to add, remove, or reorganize cabling as needed. Rear pass-through holes allow cables located on the back of the cable manager to allow cables to into the duct from the inside the rack.
