Eaton SR42UB - 42U Standard Rack Enclosure Cabinet
Overview
The Eaton SR42UB is a 42U floor-standing rack enclosure engineered to house and protect 19-inch EIA-310 rackmount IT equipment such as servers, switches, PDUs, UPS modules, and cable management accessories. It is deployed by data center infrastructure teams, network engineers, and facilities planners in core, IDF/edge, and enterprise server rooms where secure physical mounting and structured cable routing are required.
Electrically passive, this cabinet provides structural support and organization without active components. It features heavy-duty vertical mounting rails adjustable in 1/4-inch increments and a standard 42 U rack height with ample internal space to accommodate full-depth equipment and rack-mounted accessories with clearances defined by rail placement.
The SR42UB's standard depth (~43 in external/37 in usable internal) and 24-inch (600 mm) width balance floor footprint with depth to support general-purpose IT deployments. It ships fully assembled with integrated casters and leveling feet for positioning and stabilization in data centers, wiring closets, or technical rooms.
Security and serviceability are supported through locking, removable, and reversible front and rear doors, as well as removable, keyed-alike side panels that simplify maintenance access while deterring tampering. Perforated door patterns promote front-to-rear airflow for standard forced-air cooling strategies.
In typical deployment, this cabinet holds a mix of active devices and structured cabling in a central or edge rack row. It is not designed for shock isolation of seismic loads or for non-standard equipment widths outside EIA-310. Specialized racks may be required for extra-deep or wide equipment beyond standard IT gear.
