Middle Atlantic GRK Series Rack, 44 RU, 42" D

The Middle Atlantic GRK Series Rack, 44 RU with a generous 42-inch depth, is engineered for professionals who demand a rugged, space-saving solution for high-density AV and IT deployments. This welded, gangable rack delivers a compact footprint without compromising capacity, making it ideal for control rooms, broadcast environments, studios, and data centers where cable density and reliability matter most. With a solid frame top and bottom, the GRK Series provides structural rigidity that stands up to the rigors of daily rack mounting, frequent reconfigurations, and long-term use. The combination of a narrow, multi-bay configuration and deep mounting space makes it possible to consolidate equipment, power, and cabling into a single, highly organized footprint—while preserving easy access for maintenance and service. For installers who value scalable layouts, efficient cable management, and durable construction, the GRK Series is a practical, future-proof choice that helps keep equipment secure, accessible, and performing at peak efficiency.

• Rugged welded construction with solid top and bottom rails: The GRK Series is built around a sturdy welded steel frame, delivering exceptional rigidity and robust support for heavy 19-inch equipment. This solid construction minimizes flex and wobble, helping to maintain precise alignment of mounted gear over years of operation. The solid top and bottom rails further enhance durability, ensuring the rack remains square and stable even as personnel access equipment and rearrange components.
• Narrow multi-bay design for high-density cable bundles: Optimized for tight installations, the GRK Series provides a compact footprint that supports multiple bays within a single rack, enabling high-density video, audio, and data cable bundles to be organized efficiently. This design is ideal for facilities that must maximize rack space while accommodating increasingly complex cable plants, reducing collision risk and improving serviceability in crowded rack lines.
• Flexible horizontal or vertical lacing for clean cable management: The GRK Series accommodates both horizontal and vertical cabling strategies, empowering technicians to choose the best routing approach for their environment. By enabling orderly cable runs, pull-testing becomes easier, patch panel access improves, and airflow remains unobstructed, contributing to cooler operation and longer equipment life.
• Generous 44U capacity with 42-inch depth for full-featured deployments: With 44 rack units of available space and a deep 42-inch mounting depth, this rack comfortably accommodates full-size patch panels, power distribution, servers, video processors, and other standard 19-inch equipment. The deeper footprint provides room for cable slack, management arms, and connectors, simplifying installation and future reconfigurations without forcing gear tight against the rear.
• Designed for expansion and compatibility with Middle Atlantic accessories: The GRK Series is built to work seamlessly with a broad ecosystem of Middle Atlantic cable management, lacing bars, locking components, and other accessories. This compatibility enables you to tailor the rack to your exact workflow—whether you need enhanced cable routing, security features, or specialized mounting hardware—without sacrificing performance or reliability.

How to install Middle Atlantic GRK Series Rack, 44 RU, 42"D

• Step 1: Plan your layout. Assess the equipment you intend to mount, gauge cable density, and decide whether horizontal or vertical lacing will be your primary approach. Confirm the available space and ensure you have the appropriate mounting surface or enclosure location for the 42" deep rack.
• Step 2: Inspect and prepare. Unpack the GRK rack and check that all mounting rails, hardware, and accessories are present. Verify that rails are straight and undamaged, and identify the mounting hole pattern to align with 19" equipment. Prepare the workspace, ensuring proper safety measures and adequate room for cable management tasks.
• Step 3: Install mounting rails. Attach the adjustable front and rear mounting rails to the rack posts at the desired heights in 1U increments, ensuring rails are square and level. Use the provided hardware and tighten evenly to prevent rail skew that could affect equipment alignment.
• Step 4: Position and secure the rack. Move the GRK rack into its installation location and secure it to the floor or wall/structure with appropriate hardware based on site requirements. Ensure stability to support the anticipated equipment load and to prevent tipping or movement during cable management and maintenance tasks.
• Step 5: Mount equipment. Begin with heavier, larger devices first, inserting them into the 19" mounting rails. Use the standard rack screws and washers suitable for your hardware, taking care to align gear per the rack’s mounting holes. Leave adequate clearance behind front panels for clearance and airflow.
• Step 6: Route cables with consideration to lacing approach. Implement horizontal or vertical cable management paths as planned, using lacing bars or rings where appropriate. Organize power and data cables to minimize interference and optimize airflow. Label cables and patch panels for fast identification during future maintenance.
• Step 7: Final checks and documentation. Perform a final inspection to verify all equipment is securely mounted, cables are properly managed, and there is no strain on connectors. Document the layout, including rack positions, device inventory, and cable routing, to support future upgrades and troubleshooting.
• Step 8: Perform a test run. Power on equipment in sequence, confirm connectivity, verify that cooling remains sufficient, and monitor for any thermal constraints. Adjust cable routing as needed to improve airflow and reduce hotspots within the rack.
