Cable Support Systems
Cable Ladder
High strength, high-airflow cable ladder for long spans, heavy power cables and data centre routing.
- BS EN 61537
- Light & medium duty, long-span
- UK Stock
Technical overview
Dual Metal cable ladder is engineered for the heaviest containment duties — long unsupported spans, large power cables and dense data centre routes. The open rung-and-rail construction maximises airflow to keep cables cool while carrying substantial loads with minimal deflection. Robust side rails and welded or bolted rungs deliver a rigid, safe-to-walk system that installs quickly across plant rooms, risers and external cable routes.

Cable Ladder — FAQs
When should I use cable ladder instead of cable tray?
Choose cable ladder for heavy power cables, long unsupported spans and routes where maximum airflow is important — typically plant rooms, risers, data centres and external runs. Cable tray suits lighter mixed power and data loads.
What span can Dual Metal cable ladder achieve?
Support spans depend on width, finish and applied load. Our BS EN 61537 load/deflection tables give the safe working load for each configuration; our engineers can size supports for your specific loading.
Is cable ladder available for external use?
Yes. Hot-dip galvanised and stainless steel 316L options are suited to external and corrosive environments and are supplied with matching fittings and fixings.
