Tripp Lite SmartRack Industrial Enclosure, NEMA 3R, Wall Mount, Metal, Locking, Hinged Back, Fan With Thermal Switch, 28 in. Depth, 6U, Gray

The Tripp Lite SRN3RG6US is a 6U wall mount enclosure that protects network switches, patch panels, and other 19 inch rack equipment when the installation sits in a challenging environment. The cabinet is built from steel with a powder coated finish in gray and carries a NEMA 3R rating, so it blocks rain, sleet, snow, and wind driven dust. It accepts hardware up to 28 inches deep and supports a total load of 200 pounds, giving you ample space for servers, power distribution, or industrial control components.

Heat management is automatic. Two fans on the top panel start as soon as the internal temperature reaches 86 °F and shut off once the air cools. This on-demand ventilation keeps electronics within their safe operating range even in hot, enclosed areas.

Security and access are balanced carefully. A lockable front door prevents tampering, while a hinged back section swings the entire rack away from the wall so you can reach cables and ports without dismounting equipment. Adjustable rails help you set the right depth for each device, and cable knockouts create tidy entry points for power and data lines.

The enclosure ships fully assembled with mounting hardware, so installation is quick. It suits factories, warehouses, power stations, outdoor kiosks, and any other site where standard IT cabinets would struggle. Many installers also choose it for network closets inside schools or offices that need added protection.

Tripp Lite backs the enclosure with a five year limited warranty, underscoring the long service life you can expect.
