Middle Atlantic Essex Series 18RU Plexi Front or Rear Door for MMR Series Racks

The DOOR-P18 from Middle Atlantic is the smart, versatile enclosure accessory your Essex Series MMR rack needs to extend protection, organization, and visibility across front and rear configurations. Built to integrate seamlessly with Essex MMR Series racks, this 18RU smoked plexi door preserves a clean, professional look while offering easy access for maintenance, cable management, and equipment monitoring. With the ability to mount on either the front or rear of the enclosure, the DOOR-P18 delivers flexible deployment options for studios, control rooms, broadcast facilities, and data centers where space, security, and airflow are critical considerations. The smoked plexi provides discreet visibility—letting you monitor status indicators and LEDs without repeatedly opening the door—while maintaining a polished aesthetic that fits alongside other Middle Atlantic accessories and rack components.

• Flexible fit for Essex MMR Series racks: Specifically designed to attach to 18RU openings in Essex MMR enclosures, the DOOR-P18 ensures a precise fit and clean edge alignment that complements the rack’s lines and finish. This door is optimized to work with standard Essex mounting rails and corner profiles, delivering a snug, professional look that enhances overall rack integrity while protecting your gear from dust and incidental contact.
• Smoked plexiglass for visibility and style: The smoked plexi panel provides clear visibility of status indicators, meters, and front-panel LEDs without requiring removal of the door. This balance of visibility and concealment helps technicians perform quick checks at a glance, reducing downtime and improving workflow while preserving a high-end, understated aesthetic consistent with other Essex accessories.
• Front or rear mounting—swap orientation as needed: The DOOR-P18 is engineered to be mounted on either the front or the rear of MMR Series racks, giving you the flexibility to adapt to evolving room layouts, cabling schemes, or access requirements. When your space changes, you can reorient the door without replacing hardware or sacrificing security and enclosure protection.
• Durable construction with included hardware: Built to withstand daily rack use, the door combines a sturdy frame with a robust smoked panel and the mounting hardware you need for quick, tool-efficient installation. The design supports stable operation, smooth opening/closing, and dependable protection for housed equipment, even in busy environments with frequent access needs.
• Security, protection, and airflow-conscious design: While the primary role is protection from dust, accidental contact, and tampering, the smoked plexi door is engineered to minimize airflow disruption compared with fully solid doors. When used in conjunction with proper rack ventilation, the DOOR-P18 helps maintain cooling efficiency while still providing easy access and security for your critical equipment.

how to install Middle Atlantic Essex Series 18RU Plexi Front or Rear Door for MMR Series Racks

• Power down and unplug any equipment within the rack and remove cables adjacent to the mounting area to prevent interference during installation.
