Middle Atlantic MRK AV Series 44RU Rack - 44RU Open-Frame Rack without Rear Door - 36in Depth

Engineered for demanding AV and IT deployments, the Middle Atlantic MRK AV Series 44RU Open-Frame Rack is built to perform like a workhorse on even the most challenging job sites. This rugged, space-saving enclosure is purpose-built for large-scale multi-bay installations, delivering reliable support for racks, power distribution, networking, and control equipment. With a generous 44 rack-unit (RU) capacity and a deep 36-inch footprint, the MRK AV Series is a versatile solution that maximizes usable space while maintaining clear access for maintenance and cable management. Its high seismic load rating adds an essential layer of stability in environments where floor movement or structural shifts can occur, giving installers and end-users peace of mind during operation. The open-frame design without a rear door further enhances airflow and simplifies front-to-back cabling, a critical advantage for dense rack layouts and rapid equipment replacement.

• Massive 44U capacity for scalable configurations — The MRK AV Series accepts a wide range of AV and IT gear, from servers and media players to power distribution and patch panels, enabling you to consolidate equipment into a single, tidy footprint for easier management and future growth.
• Open-frame design without rear door — An open, rear-free configuration promotes improved airflow and quick access to cabling and connectors, reducing installation time and enabling straightforward maintenance and upgrades in busy multi-bay environments.
• 36-inch depth for versatile component placement — The deep chassis accommodates deeper equipment and provides ample space for front-to-rear cabling, routing, and airflow management, which helps prevent cable strain and thermal buildup.
• Rugged construction with installer-oriented features — Built to withstand the rigors of commercial installs, the MRK AV Series is designed to endure long-term daily use on large projects, delivering dependable service in demanding environments typical of multi-bay deployments.
• Seismic-certified and performance-focused design — With seismic certification and a focus on performance, this rack helps ensure stability and compliance across varied building codes, supporting safer, more reliable integration of critical AV and IT equipment.

How to install MRK AV Series 44RU Open-Frame Rack

• Plan your layout: Assess the room footprint, doorway access, and the desired multi-bay configuration. Confirm the MRK rack’s 44U capacity and 36-inch depth meet your equipment requirements.
• Position the rack: Move the open-frame rack to its planned location. Ensure the floor is level and capable of supporting the combined weight of the empty rack plus all mounted gear.
• Install mounting rails: Attach the 19-inch rack rails according to the equipment you intend to house. Verify rail spacings align with the devices’ mounting patterns and that rails are securely fastened to withstand movement during installation and use.
• Mount equipment: Begin with heavier components at the bottom for stability, then work upward. Use appropriate rails and hardware, ensuring adequate clearance for cables and ventilation. Leave space for future expansion if needed.
• Route cabling: Plan front-to-back cable management to optimize airflow and access. Label cables clearly, use color-coding where possible, and maintain slack to allow for future changes without strain on connectors.
• Secure power and safety considerations: Install PDUs and power distribution as needed, ensuring that power loads are balanced and that safety guidelines for electrical installations are followed. Check clearances around the rack to maintain accessibility and ventilation.
• Finalize and test: After mounting and cabling, verify that all equipment powers on correctly, ports align with intended connections, and that airflow remains unobstructed. Document your configuration for maintenance and future upgrades.

Frequently asked questions

• Q: What does 44U capacity mean for my install? A: 44U means the rack provides 44 rack units of mounting space (44 devices of standard 1U height). This allows for substantial equipment density, suitable for large AV and IT deployments where multiple components must share a single chassis.
• Q: Is a rear door included with this rack? A: No. The MRK AV Series 44RU Open-Frame Rack is designed as an open-frame enclosure without a rear door, optimizing airflow and front-to-back cable management for multi-bay installations.
• Q: How deep is the rack, and why does depth matter? A: The rack has a 36-inch depth. Depth matters for accommodating deeper equipment, ensuring proper cable routing, and delivering sufficient airflow to prevent overheating in dense configurations.
• Q: Is this rack seismic-certified? A: Yes. The MRK AV Series features seismic certification, making it suitable for environments where building codes require stability against movement and vibrations.
• Q: What kinds of equipment can I mount in this rack? A: The rack uses standard 19-inch equipment rails, so most 19-inch format AV and IT devices—such as servers, AV controllers, patch panels, and power distribution units—will fit within the 44U capacity when properly mounted and arranged.
