Product Overview

The Middle Atlantic U3 is a 3RU utility rack shelf that mounts non-rackmount equipment in any standard 19-inch rack. The solid shelf surface, 14.75 inches deep, supports components such as media players, modems, and source devices that lack their own rack ears. Welded steel construction with a black powder coat finish delivers the durability integrators expect from Middle Atlantic rack accessories. This listing is for a single shelf; contractors stocking volume jobs can choose the U3MP multi-pack instead.

Product Description

The Middle Atlantic U3 utility rack shelf occupies three rack spaces and provides a 14.75-inch-deep solid platform for equipment that cannot be rack mounted directly. It is one of the most commonly specified shelves in residential and commercial AV racks, handling everything from cable boxes and streaming devices to small network appliances. The one-piece welded steel body resists flexing and sagging under loaded gear, unlike lighter bolted shelves, and the black powder coat finish blends with Middle Atlantic enclosures and standard rack hardware. The solid bottom suits devices that do not rely on under-chassis airflow; when convection cooling matters, the vented U3V sibling is the better match. As a 3RU shelf, the U3 leaves comfortable clearance above mounted components for cable connections and ventilation within the rack bay. Integrators who already standardize on the U Series utility rackshelf family can drop the U3 into any 19-inch rack layout without special hardware planning. Note: the vendor lists the shelf depth at 14.75 inches; earlier catalog copy cited 14.6 inches of usable depth.
