Tripp Lite SmartRack Industrial Enclosure with Lock, NEMA 4, Wall Mount, Metal Construction, Hinged Back, 28 in. Depth, 9U, Gray

The Tripp Lite SRN4G9US is a 9U wall-mount enclosure that gives your rack-mounted equipment a safer, cleaner place to live in demanding settings. Whether you need to secure network switches on a warehouse wall or shelter control hardware near an outdoor loading dock, this cabinet keeps gear protected from water, dust, and unwanted tampering.

A steel housing with a durable powder coated finish carries a NEMA 4 rating, so it seals out wind-blown dirt, dripping water, and other airborne debris that can shorten the life of electronics. The cabinet ships fully assembled, ready to hang on a wall, and supports up to 200 pounds of equipment without the need for a separate rack frame.

Inside, adjustable front and rear rails accept devices as deep as 28 inches, giving you the flexibility to mount full-sized switches, power distribution units, or surveillance recorders. The 9U capacity makes it a practical fit for branch offices, factory floors, school labs, or any location that needs a small-footprint rack with serious environmental protection.

The rear section is hinged, so you can swing the enclosure open for quick cable management and maintenance instead of removing every component. A keyed lock on the front door keeps curious hands out, helping you meet basic security policies without adding separate hardware.

From manufacturing plants to remote kiosks, the SRN4G9US combines environmental sealing, physical security, and organized cable management in one enclosure. A five-year limited warranty from Tripp Lite adds peace of mind for long-term deployments.
