Middle Atlantic DWR-21-22 Wall Mount Rack 21U 22in Black

Product Description

The MIDDLE ATLANTIC - U.S. - LEGRAND DWR-21-22 is a wall-mounted rack cabinet designed to house AV, networking, and low-voltage equipment in professional installations. Offering 21 rack spaces (21U) and a 22-inch depth, this cabinet provides organized, secure mounting for equipment in tight or limited-floor-space environments. The black finish suits both finished and unfinished installation settings. It is typically installed by AV integrators, low-voltage technicians, and IT professionals in commercial and residential structured-wiring applications.

This wall cabinet is suited for installations where floor-standing racks are not practical. Common applications include server closets, telecom rooms, home theater equipment bays, and commercial AV equipment rooms. The 21U capacity accommodates patch panels, switches, amplifiers, and other rack-mount gear. The 22-inch depth supports standard 1U and 2U rackmount equipment found in typical AV and networking installations.

Installation Notes

Wall-mount rack cabinets of this size must be secured to structural framing or blocking rated to support the combined weight of the cabinet and installed equipment. Low-voltage technicians and AV integrators should verify wall stud spacing and use appropriately rated hardware before mounting. All power should be disconnected from any existing equipment before loading or servicing components inside the cabinet. Local building and electrical codes, including NEC low-voltage provisions, should be observed for any cabling or powered equipment installed within the enclosure.
