Eaton Tripp Lite Series SmartRack 48U Standard-Depth 4-Post Premium Open Frame Rack with No Sides, Doors or Roof

The Eaton Tripp Lite SR48UBEXPNDNR3 is a versatile 48U open frame rack designed for data center and networking applications. Its no-sides, no-doors, and no-roof configuration allows seamless baying with multiple enclosures, making it ideal for scalable server and equipment installations. The integrated baying tabs facilitate easy alignment and connection when grouping several racks in rows, optimizing space and cable management in your infrastructure.

This premium rack supports up to 3,000 pounds of equipment weight, with a sturdy 19-inch width and a depth of approximately 42 inches that maximizes floor space. The four interior vertical posts feature unthreaded square hole openings, enabling tool-less installation of compatible accessories and equipment, including PDU and cable management devices. Each rack space is numbered for clear reference, simplifying deployment and maintenance. The adjustable front and rear rails, which can be repositioned in quarter-inch increments from 4 to 37 inches, include an easy-view depth index for quick and accurate setup.

For enhanced mobility and flexibility, the SR48UBEXPNDNR3 comes with preinstalled heavy-duty 3-inch casters and leveling feet. While the casters facilitate minor position adjustments, the rack is primarily designed for stationary use. Grounding points are provided on both the front and rear, ensuring compliance with safety standards by allowing connection to your facility’s earth ground. The enclosure ships fully assembled and includes essential hardware such as M6 cage nuts and screws, stabilizing brackets, and comprehensive owner’s instructions.
