Step 4 Press down firmly on the rail until the hooks seat firmly and securely into the holes, and the spring clip latches
into place.
Step 5 Follow the same procedure to install the other rack rail.
Step 6
Use a tape measure and level to verify that the rack rails are horizontal and at the same height.
Step 7 Insert the cage nuts on to the rack in the needed square holes as shown below. When the rails are installed on
a rack unit boundary, the first two cage nuts are installed into the seventh holes above the rails' horizontal
plates. The next two cage nuts are installed into the fifth holes above the first cage nut. Finally, the two cage
nuts are installed into the fourth holes above the second cage nuts.
