The RackSolutions Adapter Brackets provide a solution to the common problems associated with installing rackmount servers into a variety of different server racks. These adapter kits allow for considerable adjustment in the installation depth of the server rack. If the server rack is too deep or too shallow, these adapter kits will solve the problem. If your server rack has round holes and your slide rails require square holes, these kits will convert round holes to square holes. This kit has an assortment of brackets that can be configured in multiple ways to solve most common installation issues.

  • Shallow Rack Extension
    Extension for shallow Rack
    For shallow depth racks, our brackets can be used for rails that extend out past the uprights.
  • Server Rail Extension
    Extension for Deep Racks
    If the rails that were supplied with your server are to shallow, the 1U adapter bracket allows the extra space needed to mount the rails.
  • Measure Mounting Depth
    What's the mounting depth?
    First, measure the mounting depth of your server rack, to determine the size of bracket that you will need.
  • Install brackets
    Bracket Installation
    Install brackets (hardware not included) in the space where the rack needs to be extended or reduced.
