Middle Atlantic ERK Series Rack – 18U, 20in Depth, Without Rear Door

The Middle Atlantic ERK Series Rack delivers professional-grade storage and organization for your most demanding IT and AV setups. Built to be both rugged and versatile, this 18U rack cabinet blends clean, modern aesthetics with practical engineering to support servers, networking gear, patch panels, and other 19-inch equipment. With a 20-inch depth and a design that ships without a rear door, it prioritizes expansive back access for cabling, airflow, and future expansion in busy data centers, control rooms, studios, and enterprise racks.

• 18U capacity for flexible gear placement: The ERK Series rack provides ample mounting space for a broad range of equipment, including servers, network switches, UPS units, KVM extenders, and AV matrices. Its 18U height is optimized to balance capacity with accessible serviceability, helping you maximize floor space without compromising performance.
• Generous 20-inch depth for clearance and cable management: The deep profile accommodates wider chassis and complex cabling, allowing you to route power, data, and management cables with ease. The extra depth also supports deeper racks, energy-efficient cooling components, and modular back-panel configurations for clean, organized installations.
• Rugged steel construction in a professional black finish: Engineered from durable steel and finished in a sleek black powder coat, this rack cabinet offers long-term protection against impact and wear. Its professional appearance makes it an ideal choice for data centers, control rooms, broadcast environments, and executive IT spaces where aesthetics matter as much as function.
• High weight capacity for even demanding deployments: With a maximum weight capacity of up to 2500 lb, the ERK Series rack supports dense, multi-rack configurations with confidence. This robust payload tolerance minimizes sag and reduces the need for frequent equipment rearrangement in growing facilities.
• Rear-door-free design for open access and versatile layout: The absence of a rear door provides unimpeded access to back panels, cabling, and power distribution. This design enhances cable management flexibility, simplifies installation of back-mounted components, and supports rapid maintenance or expansion without removing equipment from the rack.

How to install Middle Atlantic ERK Series Rack

• Unpack and inspect the rack for any shipping damage. Verify all fasteners and install hardware are present before assembly.
• Position the rack in your chosen space on a level, sturdy floor. If required, secure to the floor or wall using appropriate mounting hardware according to environmental guidelines.
• Assemble the frame and side rails, ensuring the front mounting rails are aligned for standard 19" equipment. Use level indicators to maintain a straight, plumb installation.
• Install your front-mount equipment first, starting with heavier components at the bottom to maintain stable center of gravity. Use compatible rack screws and washers to prevent vibration and wear.
• Route power, data, and management cables through the back access area. Take advantage of the open rear design to ensure clean separation of power and data runs, and use cable managers or tie-downs to minimize strain and interference.
• Verify airflow and accessibility after installation. Test system bootups, confirm all devices are properly mounted, and adjust cable routing as needed to maintain airflow and serviceability over time.
