Middle Atlantic UMS1-3.5K 1 RU Shelf

Overview

The Middle Atlantic UMS1-3.5K is a 1 RU (Rack Unit) universal multi-shelf designed for 19-inch wide racks. With a depth of 3.5 inches, it provides a stable platform for mounting compact AV or networking equipment where a full-depth shelf is not required. This model includes four partial blank panels that can be strategically placed to manage airflow and conceal components, contributing to a cleaner, more organized installation. Its black finish integrates seamlessly into most rack environments. The UMS1-3.5K is ideal for deploying small network switches, media converters, or other slim-profile devices within a structured cabling system.

Compatibility

This shelf is designed to fit standard 19-inch wide racks and is compatible with a wide range of rack-mounted equipment requiring a 3.5-inch depth. It is suitable for housing various small form-factor devices, including select network switches, wireless access points, small AV transmitters, or other low-profile electronics that do not exceed its 25 lb weight capacity.

Installation Notes

The UMS1-3.5K features two mounting points for securing equipment to the shelf surface. It installs into any standard 19-inch rack using four rack screws (not included), occupying a single rack unit (1 RU) of vertical space. The shelf's construction supports up to 25 lbs (11.3 kg), ensuring stability for its intended load. The included partial blank panels attach easily to help manage cable routing and airflow around mounted devices.
