Features

Space-Saving Wall-Mount Enclosure Houses Rack Equipment up to 23 in. Deep
This SmartRack® industrial enclosure is designed to house 12U of 19-inch rack-mount equipment, such as network switches and patch panels. Constructed from heavy-duty steel with a durable gray powder-coated finish, the SRN3RG12U has a maximum load capacity of 200 pounds (90.7 kilograms) and is suitable for indoor and outdoor applications.

NEMA 3R Enclosure Designed for Protection Against Harsh Elements
The SRN3RG12U protects its contents against the ingress of water (including rain, sleet and snow), solid foreign objects (including falling dirt) and even ice forming on the outside of the enclosure. It is ideal for a multitude of industrial sites, such as factories, construction areas, utility plants, power stations, transportation terminals, distribution hubs, warehouses and other areas where you need to keep sensitive equipment secure, organized and out of the way.

Locks Securely to Help Prevent Theft, Damage and Tampering
The fully welded steel housing locks securely with the included keys to protect its contents against theft, tampering and unauthorized access. The weather-sealed door allows easy access to equipment and cabling during installation and maintenance. Data and power cables may be routed through a bottom conduit cutout.

Easy Enclosure and Equipment Installation
This 12U industrial enclosure comes fully assembled and ready to mount to the wall with user-supplied hardware. Front and rear mounting rails adjust independently to accommodate equipment up to 23 inches deep. Hardware for mounting equipment inside the enclosure is included.

Built-In Fans Help Keep Equipment Cool and Lasting Longer
Two top-mounted fans with thermal switch activate when the temperature inside the enclosure reaches 86°F (30°C). Keeping rack equipment cool helps prevent damage and ensure optimum performance.
