Lenovo ThinkSystem 42U Onyx Heavy Duty Rack Cabinet | Enterprise Rack

Keep critical infrastructure organized, protected, and ready for growth with Lenovo’s ThinkSystem 42U Onyx Expansion Heavy Duty Rack Cabinet. Built for environments that need a stronger enclosure than a basic open frame, this cabinet provides the structure and depth required for dense server, storage, and networking deployments. At 42U, it gives teams the vertical space to consolidate equipment without sacrificing serviceability. The 23.6-inch width and 47.2-inch depth support a broad range of enterprise hardware, while the heavy-duty construction is designed to handle substantial installed weight with confidence. The Onyx finish presents a clean, professional look that fits naturally into modern data center rows. This rack cabinet is a strong choice when equipment density, physical protection, and long-term deployment planning matter. It helps standardize rack layouts across infrastructure teams that need predictable fit, stable mounting, and a cabinet built to support serious load requirements. For organizations investing in high-value hardware, that extra structural margin matters.
