Middle Atlantic DWR-RR21 Rear Rail Kit

Overview

The Middle Atlantic DWR-RR21 is a 21 rack unit (RU) rear rail kit designed to add depth and mounting points to Middle Atlantic DWR or EWR series racks. This accessory provides essential support for rear-mounting equipment like network switches, patch panels, or power distribution units, ensuring proper airflow and strain relief within the rack enclosure. Its robust steel construction with an ecoated black zinc finish offers durability for commercial and enterprise deployments.

Compatibility

This rear rail kit is specifically designed for use with Middle Atlantic DWR and EWR series racks. It features standard 10-32 rack rail threading, making it compatible with a wide range of rack-mountable equipment that utilizes this common mounting standard. It provides 21 rack units of vertical mounting space at the rear of the enclosure.

Installation Notes

The DWR-RR21 installs directly into the rear of compatible Middle Atlantic DWR or EWR rack enclosures. The 0.9-inch width and 20-inch depth ensure it fits within the standard chassis without compromising side-to-side airflow. The 36.75-inch usable height corresponds to 21 RU, allowing for substantial rear equipment mounting. Installation typically requires basic hand tools to secure the rails to the rack posts.
