Tripp Lite SmartRack Industrial Enclosure, NEMA 3R, Wall Mount, Metal, Locking, Fan With Thermal Switch, 16.5 in. Depth, 6U, Red

The Tripp Lite SRN3RR6U is a 6U wall mount enclosure designed to protect network, security, and control equipment in places where an open rack would never survive. It accepts standard 19-inch rack hardware up to 16.5 inches deep and supports a combined load of 200 pounds, so you can safely house switches, patch panels, DVRs, or automation controllers in one compact cabinet.

Constructed from steel with a durable red powder coat finish, the enclosure carries a NEMA 3R rating that helps seal out rain, dripping water, dust, and falling debris. This combination makes it a solid choice for indoor areas such as manufacturing floors, warehouses, and utility rooms, as well as sheltered outdoor sites like loading docks or service kiosks.

Security is built in. A front door that locks with the included keys discourages tampering and theft, giving you the confidence to mount valuable electronics in high-traffic or unattended spaces.

To keep internal temperatures within safe limits, a factory-installed fan automatically switches on when the air inside rises above 86°F (30°C). This hands-off cooling approach helps extend equipment life without adding extra wiring or external thermostats.

Installation is straightforward. The cabinet ships fully assembled, so you only need to anchor it to a sturdy wall, land your cables, and mount your gear. Whether you are extending a network to a production line, adding security cameras in a parking structure, or placing control hardware near heavy machinery, this enclosure delivers dependable protection and easy access.

A five-year limited warranty from Tripp Lite backs the enclosure and underscores its suitability for long-term industrial service.
