Middle Atlantic ERK Series Rack – 21 RU, 28" Depth, W/O Rear Door

Introducing the Middle Atlantic ERK Series Rack, a cost-effective, rugged enclosure designed to meet the needs of professional AV and IT environments. This economical standalone rack delivers solid protection with its fully welded frame and solid enclosure sides, ensuring reliability in demanding settings. The ERK series is engineered for flexibility, letting you gang multiple racks to create partitioned multi-bay installations that support thermal management, future growth, and streamlined workflows. Seismic-certified construction provides enhanced protection for critical gear, giving you peace of mind in seismic-prone or vibration-heavy spaces. With a compact 21 RU height and a 28" depth, the ERK rack fits neatly into smaller rooms, studios, or control suites, delivering a scalable, space-efficient foundation for servers, network gear, amps, and other equipment. The absence of a rear door in this configuration enables straightforward front-access installation and easier cable management, while maintaining strong enclosure integrity. In essence, the ERK Series Rack combines value, durability, and adaptability, helping you optimize your equipment layout today and accommodate growth tomorrow.

• Economical standalone design with solid enclosure sides provides reliable protection in a compact footprint, making it ideal for smaller rooms or studios where budget and space are at a premium.
• Flexible ganging capability lets you combine ERK units into partitioned multi-bay configurations, supporting enhanced thermal management, organized layouts, and scalable growth without replacing existing racks.
• Seismic-certified construction safeguards sensitive equipment during movement or tremors, helping maintain uptime in challenging environments such as data centers, broadcast facilities, or busy control rooms.
• Fully welded steel frame delivers rigidity and durability, resisting flex and sag under load to support a wide range of components while minimizing operational noise and vibration.
• Compact 21 RU height and 28" depth accommodate versatile placements—including under desks and in tight AV rooms—while preserving front-access airflow and straightforward cable management without a rear door.

How to Install Middle Atlantic ERK Series Rack

Prepare the installation space by selecting a level, durable floor with adequate ventilation. Confirm that the location can accommodate a 28" deep enclosure and has clear access for front maintenance and cable routing. Remove packaging and inspect the rack for any transport damage before starting assembly. If you plan to gang multiple ERK units, position the racks in the desired alignment and connect them using the appropriate joining hardware or kits recommended by Middle Atlantic. Ensure the units are level and securely positioned to prevent movement during use. Install mounting rails according to the RU height of your equipment, choosing rail kits that support the weight and form factors of your devices. Route power, network, and video cables separately to minimize interference and promote airflow; use vertical and horizontal cable management accessories to maintain an orderly enclosure. Place heavier equipment on the lower RU positions to lower the center of gravity and improve stability. Leave sufficient clearance in front of the rack for front-access maintenance and in the rear for cable trays or conduits if you require rear access in future configurations. If local codes or environmental conditions require it, consider anchoring the rack to the floor or wall and integrating seismic bracing for added stability. Finally, test system airflow, verify all connections, and reinstall any rear panels or doors if needed for additional protection or security once equipment is mounted.
