Duct-O-Bar Figure Eight Conductor Bar: Standard Indoor Enclosed Conductor Bar for US General Industrial Crane Installations 

Duct-O-Bar Figure Eight is the standard enclosed conductor bar configuration in the Duct-O-Wire electrification range — a proven, widely installed indoor conductor bar system engineered for overhead crane, hoist, monorail, and conveyor electrification applications across the broad range of general US industrial environments. The system, which gets its name from its unique figure-eight cross-sectional shape, provides safe, dependable, and fully insulated power to moving crane collectors in permanent indoor crane runway setups. It is designed for locations with standard environmental conditions where conductor bar headroom and mounting geometry are not limited. 

Duct-O-Bar Figure Eight is one of the most commonly specified and replaced conductor bar systems in the US general industrial market — an established electrification standard with an extensive installed base across automotive assembly, light manufacturing, distribution, warehousing, and food processing facilities throughout the United States. Its broad acceptance as a standard indoor conductor bar specification means Figure Eight components are among the most frequently sourced MRO replacement parts in the crane electrification category, with maintenance teams across US industrial facilities regularly sourcing individual conductors, collector assemblies, contact shoes, and accessory components to service existing Figure Eight installations without full runway replacement. 

Crane-Controls.com stocks the complete Duct-O-Bar Figure Eight range including conductors in standard amperage configurations, collector assemblies, contact shoes, hangers, splice joints, expansion joints, end caps, in-line and end feed assemblies, and junction boxes for both new installations and direct replacement of existing Figure Eight systems at US facilities.  

Crane-Controls.com's technical team provides pre-sale application support for Figure Eight system design, amperage selection, collector specification, and cross-referencing of existing Duct-O-Bar Figure Eight installations. OSHA and ASME B30 compliant installations supported.
