APC NetShelter SX3K AR9300SP 42U 600 x 1,200 mm Enclosure | Rack Cabinet

Support dense infrastructure with a full-height enclosure designed for structured rack deployments. APC NetShelter SX3K AR9300SP provides 42U of rack space in a 600 mm by 1,200 mm deep format, giving IT teams the room needed for servers, storage, switching, and power distribution in a single controlled footprint. The deeper cabinet profile is especially useful when equipment layouts demand cleaner cable paths and more space behind mounted hardware. That matters in production rooms where access, thermal planning, and maintenance efficiency directly affect operating cost. A 42U enclosure also helps standardize rack builds across sites, making it easier to replicate layouts and service procedures. For organizations that need a cabinet rather than an open frame, this model offers the physical discipline expected in enterprise environments. It is sized for serious rack density, yet still fits the common 600 mm width standard used in many data center and network room designs. When the goal is to protect valuable hardware and keep the installation orderly, this enclosure provides the right foundation.
