The SRW12US Smart Rack 12U Low-Profile Switch-Depth Wall-Mount Rack Enclosure Cabinet is designed to house EIA-standard 19-inch rack equipment in network wiring closets, retail locations, classrooms, back offices & other areas with limited floor space where you need equipment to be secure, organized & out of the way. Constructed from heavy-duty steel with a durable black powder-coated finish, the cabinet has a maximum load capacity of 200 pounds. The cabinet swings away from the wall on a sturdy hinge, allowing easy back-door access to equipment & cabling during installation & maintenance. The doors & side panels lock securely to help prevent damage, tampering or theft. The front, top, bottom & removable side panels are vented, which allows air to flow freely & keep equipment cool. The reversible doors can open left or right by rotating the cabinet 180° before mounting. Convenient top & bottom ports allow easy cable routing. The SRW12US comes fully assembled & ready to mount to the wall, or use Tripp Lite’s optional SRCASTER rolling caster kit to make it a mobile rack. Square & 12-24 threaded mounting holes & numbered rack spaces make equipment installation easy. The vertical mounting rails adjust in 7/8-inch increments to accommodate equipment up to 20.5 inches deep, such as network switches & patch panels.
