RackSolutions' Cable Management Tray is designed for managing large bundles of cables. At some point in the cable routing process, individual networking cables will be aggregated into a large group, and a cable management tray makes it easy to direct that group, while holding it in place with hook and loop straps. 

The slotted bottom allows zip ties and hook and loop fasteners to be fed through and tie down cables. Since the tray is always open at the top, it's very simple to drop cables into the tray and remove them if they need to be reorganized.
