The Middle Atlantic MRK Series 44RU Pre-Configured Rack delivers a purpose-built solution for professional AV, IT, and broadcast deployments. Engineered to a precise standard, this rack maximizes space, simplifies installation, and keeps gear organized with industry-leading cable management and accessibility. With a 44 rack unit (RU) capacity housed in a compact 21-inch-wide, 31-inch-deep footprint, it’s ideal for control rooms, studios, classrooms, rental fleets, and data/AV closets where reliability and repeatable performance matter. The MRK pre-configured design means you can deploy with confidence, knowing a robust, rack-ready enclosure is ready to accept your equipment, power distribution, and cooling accessories without the usual on-site customization delays.

• Optimized 44RU capacity in a compact footprint. The MRK Series stores a wide range of standard 19-inch equipment while maintaining accessible front and rear gear, streamlined cable pathways, and efficient airflow. This balance of density and serviceability makes it suitable for dense server racks, AV matrices, audio consoles, video processors, and network gear.
• Pre-configured for rapid deployment and repeatable setups. This rack arrives with factory-installed rails and essential cable-management provisions, so technicians can proceed with device installation, cabling, and testing without the customary rail fabrication or partial builds. It’s a dependable choice for multi-room installations, broadcast suites, and rental inventories where consistency is key.
• Durable, professional-grade construction you can trust. Built from robust steel with a protective powder-coated finish, MRK racks withstand the rigors of daily use, frequent openings, and long-term equipment loads. The rugged frame and finish project a professional appearance in any install environment—from executive rooms to production studios—while maintaining structural integrity over time.
• Comprehensive cable management and airflow considerations. Thoughtful internal organization supports neat cable routing, rear access for easy maintenance, and planning room for cable harnesses, power distribution, and cooling accessories. When cables are orderly, signal integrity improves and service calls become fewer and faster.
• Versatile compatibility for a wide range of deployments. The MRK Series is designed to accommodate AV, IT, broadcast, education, and enterprise applications. It integrates with a broad ecosystem of mounting rails, PDUs, cooling options, and accessories, enabling scalable, modular configurations that adapt to evolving gear needs.
