The shelf rails expand to match the depth of the rack.

These are not slide rails. Once the server is mounted in the chassis, it does not move.

The screws are packaged by size and type. They include:

• 12 – M6 X 16

• 12 – M6 X 12

• 4 – M6 X 4 flathead

• 4 – 10-32 X 10

• 12 – 10-32 shoulder screws

There are two sets of adapter brackets; one for round-hole racks, and another for square-hole racks. Use the set that matches your rack.
