large shelf on the front side of the rack rails.
On the front of each front rack rail, partially insert a mounting screw into the
hole containing the lowest cage nut.
Install the large shelf on the front rack rails. Rest the bottom slot of each ear on
a mounting screw.
Partially insert a mounting screw into holes 3, 6, 9, and 30 in each ear of the
large shelf.
