The B-Line series high-density network rack system uses the company’s 4-Dimension structural-support system to provide cable management for data center applications. The system uses open-frame rack solutions with a full line of rack, cable-management, power, and air-flow accessories. The design supports its maximum cable capacity without increases in physical footprint and has a low-profile in-rack electrical power distribution unit mounting that allows users to remove equipment from the back of the rack without disconnecting power. Rails are fully adjustable. Multiple ePDU mounting options offer versatility when system requirements are unknown.
