The customizable 42U rack is configured to be compatible with almost all server manufacturer’s equipment. 42U Racks feature a symmetrical frame to allow enclosures to be bayed in space-saving layouts, including side-by-side, one in front of another, in a corner, in U or T arrangements, all without the need for an expensive intermediate frame. The 16-fold frame design allows for the integrated channel above-the-joint on the horizontal frame section, which prevents liquid from collecting on the gasket and from penetrating the door or side panel when opened. The frame system provides multiple internal surfaces and points for mounting equipment and accessories. The top panel of the 42U Rack is secured with the standard eye-bolts. Whether you require a top panel for cable entry or for ventilation, it can be quickly replaced by loosening 4 screws. This stable, static design permits the use of roof-mounted cooling units. An integrated water/dust protection lip protects the gasket roof configurations.
