Middle Atlantic UMS1-5.5K 1 RU Shelf

Overview

The Middle Atlantic UMS1-5.5K is a 1 RU rack shelf designed to provide a stable platform for mounting a variety of AV, network, or security equipment within a standard 19-inch rack. Its 5.5-inch depth is suitable for compact devices, while the included partial blank panels offer a clean, finished look and help manage airflow. This shelf is ideal for integrating smaller components like network switches, media converters, or compact NVRs into an existing rack infrastructure.

Compatibility

This shelf is designed for use in standard 19-inch wide racks. Its 1 RU height makes it compatible with any rack that has available vertical space. The 5.5-inch depth accommodates devices within this dimension. The 25 lbs weight capacity supports most compact network switches, small form-factor PCs, or similar IT equipment. It is compatible with equipment that has standard rack-mounting ears or can be secured to the shelf surface.

Installation Notes

Mounting the UMS1-5.5K requires a standard 19-inch rack with at least 1 RU of vertical space. The shelf has two mounting points on each side for securing it to the rack rails. The included partial blank panels can be positioned to cover gaps around the mounted equipment. Ensure the total weight of the mounted equipment does not exceed the 25 lbs capacity. Standard rack screws and cage nuts (not included) are typically used for rack rail attachment.
