Tripp Lite SmartRack Industrial Enclosure, NEMA 3R, Wall Mount, Heavy-Duty Metal, Locking, Fan With Thermal Switch, 32.5 in. Depth, 12U, Gray

The Tripp Lite SRN3RG12UHD is a 12U SmartRack enclosure built for industrial environments where ordinary office cabinets fall short. Crafted from powder-coated steel, it holds up to 200 pounds of servers, switches, or control equipment and offers a generous usable depth of 32.5 inches, so long chassis and bulky cabling fit without a squeeze.

A NEMA 3R rating shields the cabinet from rain, sleet, snow, and wind-blown dust. That weather resistance lets you mount it on a factory wall, in a warehouse, at a loading dock, or near outdoor telecom gear with confidence. Lockable front and side doors help keep unauthorized hands away from valuable electronics.

Inside, two integrated fans cycle on automatically through a thermal switch whenever temperatures climb. This built-in cooling keeps airflow consistent and removes the need for external fan controls, helping your equipment run within safe limits around the clock.

The enclosure ships fully assembled, so installers can lift it into position, anchor it with site-specific hardware, and start populating rack units right away. Whether you need to protect PLCs beside production lines, network switches in a distribution hub, or surveillance recorders in a parking structure, this cabinet delivers reliable, space-saving protection.
