Middle Atlantic 3 RU Utility Rackshelf 14.75 Inches Deep Vented - 4 Piece - Welded Steel - U3V-4

Middle Atlantic U3V-4 3RU Vented Utility Rackshelf

Overview

The Middle Atlantic U3V-4 is a 3-rack-unit vented utility shelf built for standard 19-inch rack enclosures. Sold as a 4-piece set, the U3V-4 delivers 15 inches of usable depth and a 70-lb weight capacity — enough headroom to support heavier AV receivers, network appliances, or unmanaged switches without flex or sag. Welded steel construction means the shelf arrives rigid; no assembly-induced rack stress from flex at mounting points. The vented top surface promotes passive airflow through heat-producing equipment, which matters in densely loaded racks where thermal management is already tight.

Compatibility

Fits any standard 19-inch EIA-310 rack with two mounting points per side — compatible with Middle Atlantic's ERK, BGR, and PD series enclosures, as well as third-party open-frame and enclosed racks meeting the 19-inch EIA standard. The 15-inch usable depth accommodates most 1U–2U rack-mount appliances, including PoE network switches, patch panels, and compact NVRs. Confirm rack interior clearance before ordering: the shelf itself measures 15.38 inches from front rail to rear edge, so enclosed cabinets with rear vertical managers or cable channels may reduce effective equipment depth below the 15-inch usable figure. The 3RU height clears standard 2U equipment with minimal gap, or accepts two stacked 1U devices if weight stays within the 70-lb rated limit. For lighter loads or shallower rack profiles, evaluate whether a 1RU or 2RU variant better matches your rack shelf layout before committing to this 3RU footprint.

Installation Notes

Mounts at two points per side to standard rack rails — no cage nuts included in evidence, verify your rack rail type before ordering. The shipping weight of 28.78 lbs for the 4-piece set means each shelf unit runs approximately 7 lbs unloaded; factor this into total rack weight budgeting for floor-standing or wall-mount enclosures with rated load limits.
