AtlasIED WMA24-23 24RU Wall Cabinet With Adjustable Rails

The AtlasIED WMA24-23 is a 24RU wall-mount cabinet engineered for permanent installation in commercial AV, security, and systems integration environments. Built from 16-gauge welded steel with a durable black electrostatic powder coat finish, it is designed to handle the structural demands of densely populated rack systems in boardrooms, house of worship installations, education facilities, and distributed audio deployments.

The cabinet's split architecture — an 18-inch deep center section and a 4.5-inch rear section — ships with the back pan palletized separately, allowing contractors to send the rear section to the job site for pre-installation by other trades before the electronics arrive. The exclusive integral alignment frame supports the center section throughout its full travel range, enabling safe single-person mounting. Hat-channel adjustable rails with hash marks and fixed-position securing holes let integrators dial in rack rail depth precisely without improvising in the field.

For high-density installs, the cabinet includes 32 conduit knockouts across the top and bottom of the rear section, perforated side vents for passive airflow, and top and bottom 3RU cutouts compatible with Atlas Sound EFP Series fan panels. The rear back pan features quarter-inch boss detents on 12-inch centers for sub-plate mounting, and an interchangeable right- or left-hand cylinder lock secures the enclosure. UL 1678 listed and backed by a 60-month warranty, the WMA24-23 meets the compliance and longevity requirements of professional installed sound and AV systems work.
