What Is Ladder Rack?_
Ladder rack is a structural cable management system consisting of parallel rungs mounted on side rails, typically installed overhead in data-center hot or cold aisles. It provides a rigid, accessible path for routing fiber optic trunk cables, copper network cables, and power whips from overhead cable trays down to equipment racks. The open design allows for easy cable placement, visual inspection, and airflow, while supporting the weight of dense cable bundles without trapping heat.
Technical Details
Ladder rack is usually fabricated from steel or aluminum, with rungs spaced to accommodate standard cable ties or hook-and-loop straps. It is mounted on threaded rods or strut channels suspended from the ceiling, with splice plates for straight runs and fittings for turns or drops. Load capacity and span limits follow the manufacturer's specifications based on material and installation method; typical rung widths range from 6 to 12 inches. The open structure avoids the need for covers, simplifying adds, moves, and changes during deployment.
How Leviathan Systems Works with Ladder Rack
In our field work, ladder rack is installed above each GPU rack row to carry the dense bundles of NVLink copper cables and InfiniBand/Ethernet fiber trunks before they drop into the rack. We often coordinate with the structured cabling team to ensure ladder rack paths align with rack positions and do not obstruct overhead cooling pipes or busways.
