in the rear rail piece, counting from the unbent end.
4. Install but do not completely tighten three #8-32 x 3/8-inch flathead screws into the slots.
Tighten them when instructed to do so.

2. Locate the #10–32 5/8–inch flathead and #10–32 3/4 trusshead screws from the rack
mounting hardware kit contents.

for any partial array being installed.

bottom holes of the 2U section of post.
NOTE: Install the rails with the three beveled slots to the front of the rack and the ledge at
the bottom of the rail.
5. Install one #10–32 5/8–inch flathead screw into the bracket slot that is slightly offset from
