APC by Schneider Electric AR112 12U Single-Hinged Wall-Mount Rack Cabinet
Overview
The AR112 is a 12U single-hinged wall-mount rack cabinet from APC's NetShelter line, built for locations where floor space is unavailable — server closets, wiring rooms, retail back-of-house, and wall-mounted network/security equipment deployments. The cabinet ships unassembled, letting installers bring it through narrow doorways and stage the build in place. At 12U of rack space with a 23-inch mounting width, it accommodates standard 19-inch rack-mount equipment with the side clearance margins that most EIA-310 gear requires. The single-hinged design swings the cabinet body away from the wall for rear-access to cabling and equipment, which matters in tight spaces where you can't approach from both sides. Airflow runs front-to-rear, aligning with the intake/exhaust orientation of most network switches, patch panels, and network video recorders you'll mount inside. The black powder-coat finish is standard for rack enclosures in professional AV and security installations.
Compatibility
The AR112 accepts any standard 19-inch rack-mount equipment up to 12U total. Typical loads include 1U/2U NVRs, managed PoE switches, patch panels, fiber distribution units, UPS units sized for wall-mount deployment, and access control head-end panels. Equipment depth is constrained by the cabinet's interior clearance — verify your deepest chassis (typically 1U servers or high-port-count switches) against the interior depth before ordering. For guidance on matching rack depth to your equipment, refer to the rack and enclosure buying guide. The cabinet is part of APC's broader APC NetShelter wall-mount line; if your installation requires more than 12U or deeper equipment clearance, step up to a higher-U variant in the same family.
Installation Notes
The AR112 ships unassembled — factor assembly time into your installation schedule. Wall-mount installations require a structural stud or backing rated for the combined weight of the cabinet plus its fully loaded equipment; drywall anchors alone are not sufficient for loaded racks. The single-hinge swing path requires clear floor clearance in front of the cabinet equal to at least the cabinet's depth. Verify wall-side conduit and cable entry routes before final mounting, as rear-cabling access depends on the hinge swing rather than a removable rear panel. Overall height, width, and depth all fall in the greater-than-1-foot to 2-foot range per published specs — confirm exact dimensions from the APC product datasheet before rough-in work.
