Overview

The Middle Atlantic UMS1-11.5 is a 1U universal rack shelf designed to provide a stable mounting surface inside any standard 19-inch equipment rack. Built from steel and finished with a black textured powder coat, it offers a professional look that integrates seamlessly into studio, broadcast, or live sound rack setups. At just 1U tall, it takes up minimal vertical space while providing an 11.5-inch deep platform capable of supporting up to 25 pounds of equipment.

This shelf is ideal for placing non-rackmount items — such as small power conditioners, media players, wireless receiver units, or external hard drives — onto a secure, flat surface within your rack. The front-mount design attaches to standard rack rails, making installation quick and straightforward. For professionals looking to keep their rack organized without sacrificing space, the UMS1-11.5 delivers a simple, dependable solution from a brand well known in the rack infrastructure space.
