The SRW21U SmartRack 21U 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 and other areas with limited floor space where you need equipment to be secure, organized and out of the way. Constructed from heavy-duty steel with a durable black powder-coated finish, the cabinet has a maximum load capacity of 90 kgs (200 lbs.) The side panels and front door lock securely to help prevent damage, tampering or theft. The front, top, bottom and removable side panels are vented, which allows air to flow freely and keep equipment cool. The reversible front door can open left or right by rotating the cabinet 180° before mounting. Convenient top and bottom ports allow easy cable routing. The SRW21U comes fully assembled and ready to mount to the wall, or use Tripp Lite’s optional SRCASTER rolling caster kit to make it a mobile rack. Square and threaded mounting holes and numbered rack spaces make equipment installation easy. The vertical mounting rails adjust in 7/8-inch increments to accommodate equipment up to 16.5 inches deep, such as network switches and patch panels.
