With a 22‑inch wide footprint and a deep 31 inches, this MRK rack is designed to accommodate dense AV, IT, and network gear while preserving cable access, airflow, and serviceability. Its seismic certification and robust construction make it a trusted choice for installing contractors who need a reliable, long‑lasting enclosure that can stand up to demanding environments—from data centers to professional AV racks in multi‑bay rooms. The MRK series also offers open or removable panels and flexible access options, allowing for streamlined cabling, quick equipment changes, and minimal downtime during maintenance. If you’re aiming for a high‑performance rack that pairs durability with practical design, the MRK Series is built to deliver.

• Rugged, space‑saving design: The MRK 24U enclosure is purpose‑built to pack a full 24 rack units into a compact 22‑inch wide frame. This compact footprint helps you optimize floor space in multi‑bay installations without sacrificing room for standard 19‑inch equipment. The steel chassis is engineered for maximum stability, reducing flex and vibration while you rack up servers, switches, patch panels, and other critical gear. Its streamlined profile is ideal for cramped telecom rooms, equipment closets, or AV racks where every inch counts.
• Flexible access and serviceability: Open or removable panels, front and rear access, and configurable door options streamline deployments and maintenance. The MRK Series is designed to make cabling straightforward, with clean routing paths and generous space behind the rails to simplify cable management. You’ll appreciate uncomplicated serviceability when swapping gear, performing routine upgrades, or running complex cable plants across multiple bays—without sacrificing containment or airflow.
• Seismic certification for safer installations: Built to meet stringent seismic requirements, the MRK rack delivers certified stability for installations in regions with mandatory earthquake performance standards. This certification provides peace of mind for mission‑critical equipment, helping to protect valuable assets and ensure consistent operation during seismic events. The combination of reinforced construction and certified performance makes it a preferred solution for installations in data centers, broadcast facilities, and professional AV environments.
• Designed for multi‑bay scalability: The MRK Series is tailored for large, modular builds where multiple racks work together to support expansive equipment footprints. Its 24U height, deep 31‑inch depth, and thoughtful internal layout make it easy to align with competing bays, synchronize ventilation strategies, and optimize cable routing across rows. For installation teams planning future growth, MRK enclosures provide a dependable backbone that can accommodate additional equipment as needs evolve, without requiring a complete reload.
• Ease of installation and ongoing maintenance: From straightforward rail installation to simple front‑to‑rear access, MRK enclosures are designed to minimize install time and maximize uptime. The durable powder‑coated finish resists chips and scratches in busy environments, while the robust construction supports heavy equipment loads. With tool‑free or minimal‑tool access options on certain models, service windows are shorter and less disruptive, helping you stay on schedule for deployments and upgrades.

How to Install Middle Atlantic 24 RU MRK Series 22-Inch Wide Rack, 31-Inch Deep

Preparing to install your MRK rack involves planning for weight distribution, cable management, and future accessibility. Use the following steps to ensure a clean, secure, and scalable setup that takes full advantage of MRK’s design features:

• Step 1: Plan your layout and mounting surface. Ensure the installation area provides a solid, level surface with adequate ventilation and access for front and rear cabling. Verify that the floor or mounting framework can support the anticipated equipment weight and seismic requirements. Decide whether you’ll use front/rear door configurations and how you’ll route cables to minimize congestion and heat buildup.
• Step 2: Prepare the enclosure. Remove any protective packaging and inspect the rails, doors, and panels for compatibility with your equipment and site needs. If the model includes removable panels or adjustable rails, set them to your preferred depth range to accommodate the devices you intend to install. Keep hardware organized for a smooth assembly process.
• Step 3: Install the mounting rails. Attach the 19‑inch rails to the interior mounting points according to the manufacturer’s guidelines. Ensure rails are level and securely fastened to the enclosure frame to support heavy components. Verify that rail spacing aligns with the height of your equipment and allows proper airflow around each device.
• Step 4: Mount your equipment. Begin with the heaviest or most critical devices at the bottom to lower the center of gravity and improve stability. Assemble any patch panels, power distribution units, and switchgear in a logical sequence, ensuring cable runs have adequate slack and do not obstruct cooling paths or door operation.
• Step 5: Route and organize cabling. Use cable management features, such as rear channels and ties, to maintain tidy, accessible cable routes. Leave enough clearance behind front panels for airflow, and consider labeling for quick replacements or upgrades in the future. If rear access panels are removable, plan for easy access during maintenance or equipment swaps without fully disassembling the enclosure.
• Step 6: Attach doors, panels, and accessories. Install front and rear doors and any removable panels as required. Confirm smooth door operation and unobstructed access to mounted equipment. Add any optional accessories like cable management arms or vented panels if supported by your MRK model to optimize cooling and organization.
• Step 7: Perform a final check and power‑on test. Confirm all devices are properly seated, cables are secured, and components are not obstructing air intakes or exhausts. When powering up, monitor for errant heat buildup or airflow restrictions, and verify that seismic latches or certification requirements remain intact after placement.
