Middle Atlantic ERK Series 40RU Vented Rear Door - 64% Open Area

The Middle Atlantic ERK-VRD-40 vented rear door is engineered specifically for ERK Series 40RU enclosures, delivering robust protection without compromising airflow. Crafted from heavy-duty steel and finished in a sleek black textured powder coat, this rear door combines professional aesthetics with long-lasting durability, making it an ideal choice for demanding AV, IT, and control-room environments. Designed to optimize cooling and simplify maintenance, the ERK-VRD-40 supports high-density rack configurations while maintaining a clean, organized rack footprint.

• High-efficiency ventilation - The door features a 64% open area, a thoughtfully engineered venting pattern that promotes free air movement through the rear of the enclosure. This enhanced airflow helps dissipate heat from densely populated racks, supporting more stable operating temperatures for critical equipment and reducing the risk of thermal throttling or equipment failure in hot environments. By improving cooling efficiency, it contributes to longer component life and more reliable performance during long hours of operation.
• Rugged steel construction - Built from heavy-duty steel and finished with a durable black textured powder coating, the ERK-VRD-40 withstands daily use, resist impact, and defies the wear-and-tear typical of busy rack rooms. The finish not only provides a professional appearance but also adds an extra layer of protection against scratches, scuffs, and incidental corrosion, ensuring the rear door retains its look and function over time even in bustling installation sites.
• Precise fit for ERK Series 40RU - This rear door is specifically engineered to align with ERK Series enclosures, delivering a seamless, integrated look and dependable mounting performance. The design ensures proper alignment with standard ERK hardware, contributing to a clean, uniform rack presentation across the entire enclosure line and reducing installation time for integrators and technicians.
• Secure, maintenance-friendly access - The ERK-VRD-40 is designed to provide secure rear access for service and cable management while keeping the enclosure protected when closed. The door’s reliable latching mechanism maintains enclosure integrity during operation and transportation, while enabling quick, tool-free access when maintenance or reconfiguration is required. This balance of security and accessibility supports efficient workflows in busy facilities.
• Versatile installation and broad compatibility - Ideal for professional AV facilities, data centers, broadcast control rooms, and rental/staging environments, the rear door complements the ERK rack family with consistent dimensions and mounting geometry. Its rugged construction, combined with the vented rear design, makes it suitable for scenarios where airflow, cable management, and tidy aesthetics are all priorities in a compact footprint.
