Description
The Eaton Tripp Lite SmartRack SRN3RR6U is a rugged 6U wall-mount enclosure engineered to protect critical rack-mount equipment in demanding indoor and outdoor environments. Built from fully welded, powder-coated steel with a bold red finish, this NEMA 3R enclosure safeguards sensitive devices from rain, sleet, snow, debris, and unauthorized access.
Designed to support 19-inch rack equipment up to 16.5 inches deep, the enclosure features adjustable front and rear mounting rails and a high load capacity for reliable installation of network switches, patch panels, PDUs, DVRs, and related hardware. A gasket-sealed locking door with included keys ensures secure access, while sealed cable entry points support clean power and data routing.
To maintain optimal operating temperatures, the SRN3RR6U includes two top-mounted cooling fans with an integrated thermal switch that automatically activates airflow when internal temperatures rise. Delivered fully assembled for quick wall installation, this enclosure is ideal for industrial sites, utilities, transportation hubs, warehouses, and first-responder or security deployments where durability and environmental protection are essential.
