Tripp Lite SmartRack Industrial Enclosure, NEMA 3R, Wall Mount, Heavy-Duty Metal, Locking, Fan With Thermal Switch, 32.5 in. Depth, 18U, Gray

The Tripp Lite SRN3RG18UHD is an industrial wall mount enclosure that provides 18U of rack space for standard nineteen-inch equipment. It is built for locations where floor space is limited or where gear must stay protected from harsh conditions and unwanted access.

The cabinet uses heavy duty steel construction and a gray powder-coated finish that resists scratches and corrosion. Its NEMA 3R rating shields servers, switches and control hardware from rain, snow, dirt and dripping water, making the enclosure suitable for warehouses, manufacturing floors and sheltered outdoor installations. Locking front and rear doors include keys, helping technicians secure valuable electronics against tampering or theft.

Two integrated fans activate automatically through a thermal switch, drawing in cooler air when internal temperatures rise and helping equipment operate within safe limits. Adjustable mounting rails slide easily and accept devices up to 32.5 inches deep, while the frame supports loads up to two hundred pounds, so most power conditioners, network switches and short-depth servers fit comfortably.

The enclosure ships fully assembled. Installers only need to anchor it to a load-bearing wall, connect power to the fan kit and start populating the rack. This straightforward setup is valuable in time-sensitive deployments across production lines, distribution centers, transportation hubs or any environment where reliability, security and environmental protection are priorities. A five-year limited warranty from Tripp Lite adds long-term confidence.
