APC NetShelter SX3K AR719300 42U 600 mm Rack | Enterprise Rack Accessory

Keep critical infrastructure organized, accessible, and thermally disciplined with the APC NetShelter SX3K 42U enclosure. Built for enterprise rack deployments, this 600 mm-wide cabinet is designed to house dense equipment while preserving front-to-back airflow through perforated split doors. That matters when every degree and every service window affects uptime. The split-door design improves access in constrained aisles, making it easier to work on equipment without giving up clearance. Perforated panels support ventilation at the rack face, helping align the enclosure with modern cooling strategies in mixed-load environments. For teams standardizing rack layouts, the 42U format provides a familiar footprint for servers, network gear, and supporting infrastructure. This model is a strong fit for organizations that want a rack accessory with the structural discipline and finish quality expected in premium APC deployments. It is the kind of enclosure choice that supports cleaner cable paths, better serviceability, and a more controlled physical layer across the room.
