Tripp Lite SmartRack 18U Mid-Depth Half-Height Rack Enclosure Cabinet

The Tripp Lite SR18UB is a rack enclosure with a mid depth and a half height profile that houses up to 18U of standard 19-inch equipment. It gives system administrators, AV technicians, and small to mid-size IT teams a straightforward way to protect and organize servers, switches, and edge devices in rooms where a full-height cabinet would be impractical.

Inside the cabinet, front and rear mounting rails adjust in seconds, so you can place gear that ranges from 3 to 32.5 inches in depth without wasting space. The frame supports a 1000-pound load, giving you the freedom to mix heavy servers with lighter peripherals in the same enclosure.

Perforated doors and side panels encourage strong front-to-back airflow. If your environment demands active cooling, the top panel accepts optional fans, and open cable portals at the top and bottom let you route power cords and data lines without blocking ventilation paths.

Physical security meets compliance needs through doors that lock and reverse, plus side panels that lift off for service yet secure with their own locks when closed. These features help organizations that must follow PCI DSS guidelines or similar standards that call for controlled access to equipment.

Deployment is quick because the SR18UB ships fully assembled. Roll it into place on the included casters, set the leveling feet, connect your equipment, and the cabinet is ready for daily use. This mobility also makes the enclosure a practical choice for classrooms, demo centers, or temporary installations where layouts can change over time.

Whether you are building a compact server room, extending network capacity to a retail floor, or creating an edge computing node in a branch office, the SR18UB offers the strength, flexibility, and protection needed to keep critical hardware running reliably.
