Tripp Lite by Eaton SmartRack 12U Vertical Extension Top Hat for Server Racks - 42 in. Deep, Doors & Side Panels Included

The Tripp Lite by Eaton SmartRack 12U Vertical Extension Top Hat is the intelligent solution for growing your server capacity without expanding your floor footprint. Designed for data centers, server rooms, and network closets where space is at a premium, this 12U top-hat expansion attaches securely to the top of an existing 19-inch SmartRack system, effectively adding vertical rack height without sacrificing accessibility, security, or organization. With a generous 42-inch depth, it accommodates a wide range of equipment—including full-height servers, backup units, storage controllers, and front-loaded switches—while keeping cables, power connections, and cooling considerations neatly contained. The result is a compact, professional enclosure that preserves airflow, reduces clutter, and enhances overall data-center aesthetics—the kind of upgrade that pays dividends through improved efficiency and machine reliability.

• Maximize rack capacity with a standard-depth 12U vertical expansion that climbs above your current rack footprint without consuming floor space.
• 42-inch deep enclosure designed to fit standard 19-inch server racks, enabling deeper hardware placement and favorable cable maneuvering behind equipment.
• Lockable doors and removable side panels provide physical security for sensitive equipment while allowing quick access for service and maintenance.
• Includes top-hat mounting hardware, doors, and side panels—everything you need to complete a clean, secure top-of-rack expansion with minimal downtime.
• Durable steel construction with a professional powder-coated finish ensures long-lasting protection in busy data centers and server rooms, with compatibility for multiple mounting configurations.

How to install Tripp Lite by Eaton SmartRack 12U Vertical Extension Top Hat

• Prepare the installation area by clearing the top surface of your existing rack and verifying the compatibility of the SRTH12UB with your current SmartRack configuration.
• Remove any existing top components or obstructions from the base rack as needed to ensure a clean, level mounting plane for the top-hat extension.
• Position the SRTH12UB on top of the existing rack, aligning the 19-inch mounting rails with the rack’s front and rear rails to guarantee stable support.
• Secure the top-hat extension using the included mounting hardware. Tighten screws evenly to avoid misalignment and ensure the extension is square with the existing rack.
• Attach the doors and side panels to the top-hat extension according to the provided hardware and hinges, ensuring a secure, lockable enclosure that maintains cable management access.
• Route cables through the built-in access openings and maintain clear airflow pathways behind equipment. Verify that all front-panel equipment openings align with the rack’s front and internal cable routes.
• Test accessibility and lock mechanisms by opening and closing doors, verifying that latches operate smoothly, and confirming that side panels release for maintenance as needed.
• Load equipment in a balanced manner to preserve rack stability and minimize stress on the top-hat connectors. Ensure weight distribution remains within the design limits for safe operation.
• Perform a final inspection to confirm that the assembly is secure, cables are properly managed, and the enclosure is functional for ongoing use in a data-center environment.
