The SRW12U13G SmartRack 12U Very Low-Profile Patch-Depth Wall-Mount Rack Enclosure Cabinet is designed to house shallow equipment up to 12.75 inches deep in network closets, retail locations, classrooms 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 200 pounds. The front door features a shatter-resistant clear acrylic window that lets you monitor equipment readouts without unlocking the enclosure. Not only does the window help prevent equipment tampering and reduce acoustic noise, but it also adds visual flair to your IT installation. To ensure your valuable equipment stays secure, the side panels and front door lock. The top, bottom and removable side panels are vented, which allows air to flow freely through the cabinet to 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 through the cabinet. The SRW12U13G comes fully assembled and ready to mount to the wall (or use Tripp Lite's optional SRCASTER caster kit to make it a mobile rolling rack). Square and 12-24 threaded mounting holes and numbered rack spaces make equipment installation easy. The vertical mounting rails house equipment up to 12.75 inches deep, such as network switches and patch panels.
