With the innovative RSH custom rackmounts, virtually any component can be installed in a standard 19" enclosure without modification. Custom cut to provide a perfect opening for the face of the component that is being mounted, each RSH unit provides a neatly-trimmed installation with a perfect fit and no gaps. With accurate details on over 9,500 components in our measured unit database, chances are we have the component needed on file. Unit assembles easily in minutes and includes rear brackets to prevent the mounted component from sliding back. Fully ventilated ears and bottom promote cooling. Depending on the needs of the installation, the units can be ordered with a black textured finish (model RSH4S) or a black brushed and anodized finish (model RSH4A). Bottom depths are automatically provided in 11-1/2" , 14" , 15-1/2" , 17-1/2" , or 20-1/2" styles. Custom rackmounts will accept any component up to 17-3/4" wide. Individual custom faces (less rack ears and shelf bottom) are also available in a black textured finish (model SFACE) or a black brushed and anodized finish (model AFACE). LCD rackmounts also available to mount most LCD monitors with up to a 17" screen size or with a maximum width of 17-3/8". NOTE: custom rackshelf height is specified at the factory based on physical restrictions. Visit middleatlantic.com to find heights on all measured components, or design the system in RackTools® or Visio® Blocks, which are both updated regularly with the latest components.
