If you are installing the support tray in a rack with wide-hole spacing, install the

using the bottom and the middle hole that you marked on the rack’s front surface 

(see Figure 1-5).
An internally threaded stud projecting from the front of the support tray flange 

accepts the captive fastener on the front of the system.
