Middle Atlantic AXS Series MRK-4431AXS-26 Roll-Out Rack

The MRK-4431AXS-26 from Middle Atlantic is a premium AXS Series rack designed to revolutionize how you install, service, and maintain equipment in professional AV and IT environments. This MRK enclosure ships as a factory-assembled system, delivering quick deployment and reliable, organized access to rear connections. Ideal for space-limited installations, the MRK-4431AXS-26 enables technicians to roll entire bays out for service, then return them smoothly to the cabinet with minimal disruption. With its patented design, it combines robust construction, thoughtful cable management, and effortless access to maximize uptime and simplify complex installations.

• Roll-out bays for rapid service access. The MRK-4431AXS-26 features a patented roll-out mechanism that pulls entire equipment bays forward, granting unobstructed access to rear ports, power connections, and cable runs. This design minimizes the need to remove gear from the rack, reduces service time, and lowers the risk of disconnecting the wrong cables during maintenance. By bringing the connectivity layer to the operator, it supports quick swaps, firmware updates, and routine checks without the heavy lifting or reorganization typically required in traditional racks. In busy facilities, this translates to faster turnarounds and greater equipment availability.
• Factory-assembled reliability in a compact MRK enclosure. The MRK-4431AXS-26 is delivered as a complete, factory-assembled system within an MRK enclosure. This ensures precise fit and finish, with hardware pre-aligned for seamless integration. The enclosure design emphasizes solid rigidity, vibration resistance, and long-term stability, even in environments with continuous access and frequent roll-out cycles. The combination of a ready-to-install system and the MRK enclosure architecture streamlines procurement, reduces installation labor, and yields a cohesive, professional appearance in conference rooms, broadcast studios, data centers, and other demanding settings.
• Space-conscious solution for demanding installations. Space-limited environments demand clever use of footprint and front-to-back accessibility. The AXS Series concept, embodied by the MRK-4431AXS-26, supports efficient utilization of bays while preserving rear access for cabling. Its design prioritizes minimal obstruction to airflow, quiet operation, and safe handling of equipment during roll-out. For installations where every inch matters—such as control rooms, compact server rooms, or portable AV setups—the MRK-4431AXS-26 delivers a flexible, scalable approach to rack management.
• Enhanced cable management and organization. Across the MRK-4431AXS-26, engineers have integrated thoughtful cable pathways, labeling options, and strain relief strategies to keep cables tidy during roll-out and return. A clean separation between power and data paths reduces interference and simplifies maintenance. Clear labeling and accessible rear connections expedite troubleshooting and upgrades, while protected routing minimizes wear on cables during frequent rollouts. This attention to cable discipline supports reliability in live environments where downtime must be minimized.
• Durable, future-ready performance. Built to survive demanding professional use, the MRK-4431AXS-26 combines sturdy materials, precise tolerances, and a design that accommodates evolving equipment footprints. The AXS Series rack can adapt to a growing array of devices—servers, audio processors, video routers, power distribution units, and other rack-mount gear—without sacrificing ease of service. This future-ready approach helps integrators future-proof installations, enabling straightforward expansions or reconfigurations as tech demands shift. It’s a strong foundation for reliable performance in broadcast, live events, control rooms, and enterprise AV environments.

How to install MRK-4431AXS-26

• Prepare the installation site. Verify that you have a compatible MRK enclosure and that the mounting surface is clean, level, and able to bear the load of the fully assembled rack. Confirm ventilation and cable routing paths are clear to prevent obstructing the roll-out mechanism. Have the necessary tools on hand, including screwdrivers, torque wrench, and cable management accessories standard to your facility’s workflow. Reading the user manual before unpacking can help you anticipate any site-specific considerations and ensure a smooth installation.
• Unpack and inspect. Carefully unpack the MRK-4431AXS-26 and visually inspect for any transit damage. If the package includes hardware bags, cross-check the contents against the packing list. Confirm that all rollers, rails, and safety features are intact. If anything appears damaged, document it with photos and contact the supplier before proceeding. This step minimizes the risk of installation delays caused by component issues discovered mid-build.
• Position within the MRK enclosure. Place the roll-out rack module into the designated bay of the MRK enclosure, aligning mounting points with the enclosure frame. Ensure the chassis sits securely and square to the cabinet so that the roll-out mechanism operates smoothly without rubbing or binding. Tighten hardware to the recommended torque values to prevent vibration or misalignment during operation. Take care to maintain alignment with any existing vertical cable organizers and rails.
• Route power and data thoughtfully. Before rolling out, organize power, network, and signal cables with clear labeling. Use separate pathways for high-current power and sensitive data to reduce the potential for interference. Attach cable management accessories to route cables along internal guides, ensuring no strain on connectors as the bays extend. As you test the rollout, verify that rear ports align with corresponding cables and that there is no obstruction when the bays are in the rolled-out and rolled-back positions.
• Test, balance, and finalize. With the bays rolled out, perform a basic functional check of all connected devices: confirm power presence, port activity, and signal integrity. Cycle the bays a few times to ensure smooth operation and to identify any rubbing or resistance early. Once validated, roll the bays back and secure them in the enclosure. Document the configuration, including device positions and cable routing, to streamline future service visits and upgrades.

Frequently asked questions

• What is the MRK-4431AXS-26? The MRK-4431AXS-26 is an AXS Series roll-out rack from Middle Atlantic designed to provide rapid, rear-access to equipment connections within an MRK enclosure.
