Middle Atlantic R4 Series R4CN-5130B Open Rack Frame

The Middle Atlantic R4CN-5130B Open Rack Frame is engineered for professional environments where reliability, scalability, and clean cable management are non-negotiable. This frame scratches the itch for efficient space utilization while delivering rock-solid support for a broad range of equipment. With a 51U rack height and a standard 19" width, it provides generous space for servers, audio-visual processors, network gear, and power distribution modules, all within a single, accessible footprint. The 30" depth accommodates larger, deeper components and allows ample room behind equipment for robust cabling and airflow. Built from rugged steel and finished in a sleek black powder coat, the frame is designed to withstand demanding installations—from broadcast studios and post-production suites to data centers and control rooms. Exceptional weight-bearing capability (up to 2000 lb) ensures that even fully loaded configurations stay stable and secure. As part of the R4 Series, this open rack frame benefits from Middle Atlantic’s expertise in modular, configurable rack systems, giving you a solid foundation for future expansion, custom panels, and enhanced cable management solutions.

• High-capacity 51U open frame: The R4CN-5130B offers 51U of versatile rack space in a standard 19" format, enabling you to accommodate a wide array of equipment—from servers and video processors to audio interfaces and patch panels. The open-frame design simplifies installation, reduces obstruction during rack mounting, and fosters better airflow, which helps keep temperatures in check and equipment operating at peak performance.
• Generous 30" depth for deep gear and clean cabling: With a deep 30" profile, this frame comfortably houses deep chassis, large power distribution units, and cable-management accessories. The extra depth makes it easier to route cables behind equipment, organize multi-port connections, and maintain clean front-to-back airflow paths—critical for reliability in dense rack deployments.
• Durable steel construction with a black finish: Constructed from rugged steel and finished in a professional black powder coat, the frame balances toughness with a refined appearance suitable for production studios, control rooms, and data environments. The finish offers resistance to scuffs and corrosion, helping maintain a professional look even after years of use and rough handling during installations or relocations.
• Substantial weight capacity (up to 2000 lb): The frame’s robust design supports heavy, multi-device racks without compromising stability or safety. This makes it an excellent choice for full racks of servers, audio-visual processors, networking gear, PDUs, and other equipment that demands a sturdy, vibration-resistant base.
• Seamless integration with the R4 Series ecosystem: As part of the Middle Atlantic R4 Series, this open rack frame is designed to integrate with a wide range of compatible panels, doors, rails, and mounting accessories. This ecosystem enables highly customized configurations, easy future expansions, and streamlined cable management that aligns with your workflow and space constraints.
