Middle Atlantic 21 Space (36 3/4IN. ) Sectional Wallrack Fits 20IN. Deep Equipment DWR - DWR-21-22

Middle Atlantic DWR-21-22 21U Pivoting Wall Rack

Overview

The Middle Atlantic DWR-21-22 is a 21-space (21U) sectional wall rack designed for installations where floor space is unavailable and rack-mount equipment needs to be wall-deployed — telecom closets, head-end rooms, small security equipment rooms, and AV infrastructure alcoves. The DWR-21-22 provides 36.75 in. (93.3 cm) of usable vertical height and 20 in. (50.8 cm) of usable depth, accommodating the vast majority of 1U through 2U rack-mount equipment including NVRs, network switches, patch panels, and UPS units in a single enclosure. UL-rated load capacity is 250 lbs (113.4 kg) — sufficient for a fully populated mix of network and security hardware without staging concerns. The steel, black wrinkle powder coat construction is built for commercial environments; the rack is TAA compliant and manufactured in the USA. Seismic rating (UL 7278183) makes this suitable for deployments in seismic zones where rack anchoring and load certification matter for code compliance. Forward Compatible design means accessories and future Middle Atlantic components from the Middle Atlantic rack and enclosure line integrate without modification.

Compatibility

The DWR-21-22 accepts standard 19-inch rack-mount equipment across all standard rack unit heights (1U, 2U, 4U, etc.) up to 21U total. Usable depth of 20 in. fits most 1U network switches, 1U–2U NVRs, 1U patch panels, and shallow UPS units — verify your deepest unit's chassis depth against the 20 in. usable figure before ordering. The forward rackrail configuration positions equipment toward the front of the enclosure; rear-cabled equipment requiring pass-through to a wall conduit or structured cabling system works within the 22 in. total rack depth. The DWR series is designed to accept Middle Atlantic sectional wall rack accessories including rack shelves, cable management, and blanking panels sold separately. For NVR and video recorder deployments, confirm that airflow requirements of the installed units are compatible with the open-frame wall enclosure format — no front door is included on this model.

Installation Notes

Mounting footprint dimensions: 23.4 in. wide × 43.75 in. tall (59.4 × 111.1 cm). Plan wall blocking or structural backing rated for the combined rack-plus-payload weight; at full 250 lb load plus the 80.1 lb rack itself, total wall load approaches 330 lbs — standard drywall anchors are not adequate. No front door is included; factor this into any security or dust-management requirement for the installation environment. Shipping weight is 116.6 lbs (52.9 kg) — plan accordingly for single-person installation logistics. Seismic compliance under UL 7278183 requires correct anchor hardware and wall substrate — consult your local code authority for seismic zone requirements.
