Middle Atlantic 3SP Anod Drawer W/lock - D3LK

Middle Atlantic D3LK 3U Locking Steel Rack Drawer

Overview

The Middle Atlantic D3LK is a 3U rack-mount drawer built for integrators who need secure, accessible storage inside a standard 19-inch equipment rack. The D3LK occupies 3 rack units (5.25 in) and extends to a 15.56-inch depth — enough room for spare hardware, patch cables, small UPS batteries, or documentation binders that need to stay with the system but out of sight. The integrated lock keeps contents secured in shared equipment rooms, colocation environments, or any rack where unauthorized access is a real concern. Finished in black brushed anodized steel, it blends cleanly with most rack enclosures and resists corrosion in low-humidity indoor environments. At 12.37 lbs unloaded and a rack accessory rated to 50 lbs UL-verified load capacity, it handles everything from small tools to network gear without flexing or binding under weight.

Compatibility

The D3LK mounts to any standard EIA-310 19-inch rack rail system using 2-point mounting — compatible with Middle Atlantic rack enclosures including the BGR, ERK, MFRGEAR, and WT series, as well as third-party open-frame and enclosed racks conforming to the 19-inch EIA standard. The 3U footprint fits both shallow and deep rack bays; at 15.56 inches of drawer depth, verify your rack's usable interior depth (typically 24–31 inches in a standard network rack cabinet) leaves clearance behind the drawer for cable management or rear-mounted gear. Not designed for outdoor enclosures or environments with condensation — steel construction without conformal coating is rated for controlled indoor use only.

Installation Notes

Mounts via 2 points to standard rack rails; no additional hardware kit is required beyond rack screws appropriate for your rail type (cage nut or threaded). The drawer slides on a fixed track — confirm rail spacing matches EIA 19-inch standard before ordering. Product weight is 12.37 lbs; factor shipping weight of 17.94 lbs when calculating freight for multi-unit orders. UL-rated load capacity is 50 lbs — do not exceed this limit, particularly with dense networking hardware or battery modules. A rack planning guide can help confirm unit placement when load distribution across multiple shelves matters.
