Description
The Tripp Lite SR25UBEXP is a 25U SmartRack standard-depth expansion enclosure designed for scalable data center and network deployments. Built for environments where multiple racks are bayed together, this expansion model includes locking front and rear doors but no side panels, allowing seamless integration into row-based configurations.
With a high load capacity and adjustable vertical mounting rails, the SR25UBEXP supports a wide range of 19-inch EIA-compliant rack equipment, including servers, network switches, UPS systems, and patch panels. The enclosure features massive front-to-rear ventilation, making it suitable for hot aisle/cold aisle airflow designs.
Preinstalled casters and leveling feet allow easy positioning, while the open bottom and vented, removable top panel simplify cable routing and airflow management. Toolless mounting rails support vertical PDUs and cable managers, helping reduce cable clutter and improve serviceability. This expansion rack is ideal for data centers, IT rooms, and enterprise environments requiring modular growth and reliable equipment protection.
