Description
The Eaton Tripp Lite SR45UBEXP is a 45U SmartRack standard-depth rack enclosure cabinet designed as an expansion unit for baying multiple cabinets together in data centers. It includes front and rear locking doors, a vented top panel, and an open bottom for superior cable routing and airflow. Without side panels, this model facilitates efficient hot aisle/cold aisle configurations and seamless equipment access when bayed.
Featuring adjustable vertical mounting rails, toolless PDU/cable manager mounting slots, and a heavy-duty 3500 lb stationary load capacity, the SR45UBEXP is built for flexibility and high-density environments. It ships fully assembled on pre-installed casters and supports various rack-mount accessories from the SmartRack® ecosystem.
