Description
The Tripp Lite SmartRack SRN3RG6U is a rugged 6U wall-mount industrial enclosure designed to protect critical rack-mount equipment in demanding indoor or outdoor environments. Built from heavy-duty, powder-coated steel, this NEMA 3R-rated enclosure safeguards networking and IT hardware from rain, sleet, snow, dust, and tampering.
With adjustable front and rear mounting rails, the enclosure supports standard 19-inch rack equipment up to 16.5 inches deep, including switches, patch panels, PDUs, and small servers. A gasketed, locking door with included keys helps prevent unauthorized access, while sealed cable entry points allow clean and protected power and data routing.
Integrated top-mounted fans with a thermal switch automatically activate when internal temperatures rise, ensuring proper airflow and extending equipment life. Shipped fully assembled and ready for wall installation, the SRN3RG6U is an ideal solution for industrial sites, warehouses, utilities, transportation facilities, and remote network deployments where space, security, and environmental protection are critical.
