Mighty Mo 20 channel racks are designed to provide greater flexibility and optimum efficiency to any size network. The top trough with a built-in waterfall provides bend radius control and efficient patch cable routing. Honeycomb side rails on all depth channel racks provide the ultimate in distribution cable management. On 16-1/4" and deeper channel racks, honeycomb side rails and airflow baffles combine to create a patented system that manages intake and exhaust air from side vented equipment.
