The MRK Series emphasizes quick access and ease of service, so technicians can slide in or remove gear without wrestling with rigid enclosures. In addition to its workload-ready frame, MRK Series racks are designed with seismic considerations in mind, providing a robust solution for environments where movement or vibration control is a priority. For contractors and installers, the MRK Series represents a reliable backbone for scalable systems that can adapt as projects evolve, lowering total cost of ownership over time.

Beyond raw capacity and airflow advantages, the MRK Series excels at practical usability. The open-frame design supports a modular approach to mounting rails, accessories, and cable management solutions, which translates to faster installs and simpler future upgrades. This rack is compatible with standard 19-inch equipment footprints, ensuring broad compatibility with a wide range of racks, patch panels, switches, power distribution units, and audio/video processors. Its sturdy frame and well-considered geometry enable secure, tidy installations in control rooms, media centers, telecommunication rooms, and other professional environments. For installers who manage complex, high-traffic IT and AV installations, the MRK Series 44RU open-frame rack provides a stable, adaptable foundation that keeps systems organized, accessible, and ready for immediate service when needed.

Whether you’re consolidating equipment for a single-operator studio, coordinating multi-rack deployments in an enterprise, or setting up a data-intensive AV distribution network, the MRK Series delivers the versatility and resilience you require. The combination of 44 rack units, a 26-inch depth, and seismic-certified performance makes it a trusted choice for professionals who demand both capacity and reliability without compromising on space efficiency. In the field, this translates to quicker installs, easier maintenance, and the freedom to reconfigure racks as your systems grow or change. The MRK Series is more than just a cage for equipment—it’s a strategic building block for scalable, dependable, professional-grade installations.

How to install Middle Atlantic MRK Series 44RU Open Frame Floor Standing Rack

• Plan the layout and site requirements: verify floor levelness, clearances for rear equipment access, and the intended flow of cables. Consider future expansion and ensure there is adequate ventilation and space for cooling.
• Prepare the installation area: clear the workspace, gather mounting rails and any optional accessories, and identify anchor points if floor anchoring is required by code or seismic considerations.
• Assemble the open-frame rack: attach any required vertical mounting rails and cross members per the manufacturer’s instructions. Ensure rails are properly aligned to support standard 19-inch equipment and to provide balanced weight distribution.
• Install equipment and manage cables: mount heavier components toward the bottom to improve stability, then route power and data cables with adequate separation for airflow. Use cable managers, ties, and labels to keep the installation organized and accessible for maintenance.
• Secure and test: anchor the rack to the floor if necessary, perform a stability check, and power up the equipment to verify proper electrical and network connectivity. Confirm that ventilation paths remain clear and that accessibility to front and rear of the rack is preserved for future service needs.
