AtlasIED WMA12-23 12RU Steel Wall Cabinet With Adjustable Rails

The AtlasIED WMA12-23 is engineered for systems integrators and AV contractors who need a reliable, field-adaptable wall mount rack enclosure in commercial installation environments. The 16-gauge welded steel construction with a black electrostatic powder coat finish provides the structural integrity required for permanent installs in education, corporate AV, house of worship, and distributed audio systems. The 12RU panel space, 18-inch center-section depth, and 4.5-inch rear section accommodate a practical range of DSPs, amplifiers, power conditioners, and signal processors without overextending a wall footprint.

The exclusive integral alignment frame supports the center section through its complete travel range, eliminating sag and ensuring square alignment during and after installation. Hat-channel rail adjustment with top and bottom securing holes allows front-to-back rail positioning without improvisation on the job site. The mirror-image back pan accepts left or right hinging regardless of orientation, and ships separately on the same pallet so the rear section can be dispatched to a job site independently for pre-installation by other trades — a practical workflow advantage on multi-contractor projects.

Internal bracing doubles as cable management and pass-through routing, while perforated side vents in the center section support thermal management for installed electronics. The rear section's 1/4-inch boss detents on 12-inch centers give contractors a clean anchor system for custom sub-plates in aluminum, steel, or plywood. Thirty-two conduit knockouts across the top and bottom of the rear section accommodate standard and concentric conduit sizes, keeping cabling infrastructure clean and code-ready.
