Middle Atlantic UD4 4U Rack-Mount Utility Drawer

Overview

The Middle Atlantic UD4 is a 4-rack-unit utility drawer designed for equipment rooms, security head-end racks, and AV/IT enclosures where you need accessible, organized storage without sacrificing rack space efficiency. At 15.85 inches deep and rated to 50 lbs (UL-verified), the UD4 handles everything from spare SFPs and patch cables to DVR remotes and installation tools — keeping frequently accessed items at the rack face rather than scattered across a floor or shelf. The UD4 ships in a black powder coat finish that matches standard Middle Atlantic rack enclosures and open-frame systems.

Compatibility

The UD4 installs in any standard 19-inch EIA-310 equipment rack using two front mounting points — compatible with Middle Atlantic ERK, RK, and WM series enclosures, as well as third-party 19-inch open-frame and enclosed racks from Chatsworth, Rittal, Tripp Lite, and similar manufacturers. At 4 RU tall and 19 inches wide, it occupies a standard rack footprint with no modifications required. The 15.85-inch drawer depth suits both shallow-depth wall-mount enclosures and full-depth floor racks — verify your enclosure's usable interior depth before ordering if clearance is tight. Pairs naturally with rack-mount accessories such as patch panels, cable management, and PDUs in mixed-use head-end builds.

Installation Notes

Mount using the two front-panel rack ears — no rear support rail required for loads within the 50 lb UL capacity. For heavier or unbalanced loads approaching the weight limit, verify your rack's rail-to-rail spacing and front-rail thread type (M6 cage nut or 10-32 tapped) before ordering rack screws. The powder coat finish is non-conductive; ensure proper rack ground bonding via a separate grounding strap if the installation requires chassis ground continuity.
